Myth Busters Klaus Brun and Rainer Kurz discuss what AI is and isn’t, its shortcomings and strengths, and how it’s changing the turbomachinery and power generation industries. 

TurboTime Podcast: Turbomachinery in the Age of AI and ML

In part II of the TuboTime episode on designing turbomachines, the Myth Busters, Klaus Brun and Rainer Kurz, discuss the accuracy of these design tools, which benchmark testing is still required, and current state-of-the-art tools.

How accurate are these tools? Are the software limitations a part of the software, or are they human input issues?

 It depends on the software, right? There are situations where you need to be fairly accurate. Most finite element analysis (FEA) and computational fluid dynamics (CFD) are reasonably accurate, depending on the input of your boundary conditions. You really need to consider what you're trying to accomplish. Structural FEA is more advanced than CFD. Additionally, the equations being solved are fundamentally more linear, and therefore, the expected results tend to be more precise. You can generally expect to be within a couple of percent. In contrast, with CFD, the equations, as Rainer mentioned earlier, the Navier-Stokes equations, are highly complex and nonlinear partial differential equations. These equations are difficult to solve, and you can end up with very inaccurate results because many approximations are made, especially regarding turbulence modeling and boundary layers. The fidelity of the model is essential since you can't delve down to a molecular level; there's a limit to the size at which you can operate before you must make turbulence assumptions and consider steady state versus transient conditions. There are numerous opportunities for error here, and those are some of the significant ones.

 The issue is fundamentally this: What problem are you trying to solve? If you ask a designer to create a new compressor stage that aligns with the experience level of that company's database, you can likely determine things like efficiency or head-making capability, particularly in terms of aerodynamics, probably within a few percent without ever testing it. However, if you are dealing with something for which there is no reference data—essentially operating in uncharted waters and relying solely on your code—the accuracy is significantly and dramatically lower than that.

How accurate are advanced computational tools like CFD and FEA? Find out in part II of designing turbomachines with the Myth Busters.

TurboTime Podcast: Designing Turbomachines - Part II

In this episode of the TurboTime podcast, Myth Busters Klaus Brun and Rainer Kurz discuss the design of turbomachines. They describe the typical design process for a turbomachine, outline the required engineering tools, and explain each analytical tool's function: finite element analysis, computational fluid dynamics (CFD), and rotor and blade dynamics. They also discuss how compressors, pumps, and turbomachines were designed before these advanced computational tools existed.

TURBO: Can you describe the typical design process of a turbomachine and what engineering tools are required?

 You begin with what's known as a 1D analysis, then move to a 2D analysis, also called a blade passage flow analysis. After that, you proceed to 3D and conduct some testing before refining your geometry. In essence, that's the aerodynamics part, right? However, there’s an initial step that is often overlooked, which is your own experience. You start your design based on your experience and your existing machinery portfolio. If you’re a turbomachinery manufacturer with 50, 60, or 70 years in the field, you’ve likely worked on various types of machines. Therefore, before designing a new machine, impeller, or expander, you review your existing portfolio; that's usually your starting point. You examine what's closest to your needs within that portfolio to determine if you can build upon it or if you need to start from scratch. Besides the aerodynamic design process, there's also a review of structures and dynamics that runs parallel to your aerodynamic process. You perform aerodynamic design followed by structural checks. Essentially, you assess the solids and dynamics to ensure there’s no risk of failure due to vibration. You conduct these evaluations throughout to avoid potential failures. These are generally well-known considerations. Additionally, a third aspect that often gets overlooked is manufacturability. It’s crucial to ensure that what you're designing can actually be manufactured, as it wouldn’t make sense to design an impeller or a machine that ultimately cannot be produced due to a lack of available technology or machinery. This consideration relates closely to materials, so manufacturability and materials fall into the same category, requiring a review of your materials, coatings, etc., throughout the design process to ensure that your design is feasible for production.

 I’d also like to point out that, as engineers, we don't design these machines out of thin air. There’s usually a use case, a customer, or a market assessment that indicates we need something that fits specific requirements. This could be a gas turbine that produces 20,000 horsepower or a compressor that can deliver more throughput than what my competitors can achieve within a given casing size, and so on. Then, we enter a process where engineering is asked, "Hey, can you guys do that?” Of course, someone also inevitably asks if we can achieve that at a cost that makes the project feasible. Yes, Klaus is absolutely right; this essentially defines the playground we work within. From there, we move from what could be considered a rough draft, using our experience, to increasingly refined concepts. Ultimately, you'll end up with some CFD simulations, and after building the first machine or prototype, there will be some testing to follow.

Do engineers overrely on computational tools? The Myth Busters deep dive into engineering tools, such as CFD and FEA, used to design turbomachines. 

TurboTime Podcast: The Turbomachinery Design Process - Part I

This episode of the TurboTime podcast features an onsite interview from our Turbo Tour of EthosEnergy’s Light Gas Turbine and Performance Center Facility in Houston. Assistant Editor James Cook talks with Daniel Tegtmeier, Director of EthosEnergy's Performance Center, about remote monitoring and operations, the changing energy landscape, and the benefits of remote start/stop and virtual capabilities.

Q: How does remote monitoring keep simple-cycle assets viable in a market focused on renewable energy?

 If you think about a machine built 20+ years ago and its efficiency, it still has a place in the market when competing with renewables. It’s not like it used to be though—these units used to run wide-open, 24/7. They’re now intermittent assets competing with renewables and zero-cost fuels, but once the wind stops blowing and the sun stops shining, that load is gone.

These are simple-cycle configurations, so they can come online quickly and be at 100 - 120 MW in less than an hour. So, you’re going to staff a facility 8,000 hours per year in case they call you up? That’s part of what we do and the justification for remote operations—you need the intermittent load from simple-cycle assets in rapid fashion, but you can’t afford to staff these places full-time.

Q: In addition to that justification, are there any safety improvements delivered through remote start/stop and control capabilities?

 Economics seems to drive most decision processes behind whether you’re remotely operating a facility or not; however, there’s a huge safety aspect. You don’t need people there 24 hours a day around equipment with a lot of pent-up energy, so exposure levels drop dramatically. For the most part, these machines are designed so well and over-engineered from day one that they’re conducive to [remote monitoring].

In this episode of the TurboTime podcast, Daniel Tegtmeier, Director of EthosEnergy’s Performance Center, talks about remote operations and monitoring.

In part two of this episode of the TurboTime Podcast, Klaus Burn of Ebara Elliott Energy, and Rainer Kurz of RKSBenergy LLC, discuss surge and choke on a compressor map. They explain where they occur on the map, what happens to the compressor when they operate in these extremes, and about transient operation of a compressor.

Brun explained surge: “On the left side of the map you have surge, and on the right side is choke, overload, or stonewall. The most basic definition of surge is the compressor head cannot overcome the system-imposed pressure, i.e., pressure on the outside on the suction and discharge, and the compressor is not making enough head to overcome that pressure differential. So instead of the flow moving forward through the compressor, the flow suddenly turns around and goes backward through the machine until that pressure balances again, at which point the machine can overcome that head. Then it starts a process again. And that becomes a circular process—you get into these surge cycles, and it's a fairly complex thing.”

Kurz emphasizes that surge is an interaction between the compressor and the system around it, “meaning the compressor by itself doesn't surge,” he said. “If the system forces the compressor to make more pressure ratio than under whatever conditions the compressor is going to make, then the gas thus what it wanted to do in the first place, which is go from the high pressure to low pressure, meaning it goes backward through the compressor. The tricky part with that is on the compressor map, we show what the compressor does. So, the map by itself and that surge line on the map is essentially something you derive from the compressor performance.”

The Myth Busters, Klaus Brun and Rainer Kurz, talk about surge and choke on a compressor map. 

TurboTime Podcast: Part II: Surge and Choke with the Myth Busters 

In this two-part episode of the TurboTime Podcast, Klaus Burn of Ebara Elliott Energy, and Rainer Kurz of RKSBenergy LLC, discuss compressor maps. The duo explains what compressor maps are, what they are useful for, how they fit into the process, and where head, flow, and efficiency islands fit in.

“In its most basic form, a compressor map is a graphical representation of how a centrifugal compressor behaves,” Brun said. “It's somewhat of an oversimplification because more factors play into it; but overall, it gives an accurate representation of what a compressor does within the system that it operates. A standard compressor map has an X and Y axis. The Y axis has something called head—isentropic or polytropic head. Sometimes you also see pressure ratio or a discharge pressure or a fixed section pressure. On the X axis is flow, and most of the time it’s volumetric flow. Sometimes you see mass flow, but that's not very common. Compressor maps also have a surge line on the left and on the right side of the map you have a choke or stonewall area. And finally, you have efficiency islands, and they correspond to the efficiency of the compressor. Not all compressor maps show them.”

Kurz further described efficiency islands: “Efficiency islands refer to the fact that these maps are three-dimensional, but we can only put them in two dimensions on paper. The three axes you want to display are head, flow, and efficiency. You use the efficiency lines in a very similar way to elevation lines. Also, the coordinates of the map that are directly affected by the compressor aerodynamics are head and flow. You can translate head into pressures or pressure ratios, and you can translate actual flow into mass flow, but ultimately what happens aerodynamically in the compressor is described by head and actual flow.”

The Myth Busters, Klaus Brun and Rainer Kurz, talk about compressor maps—what they are, how they are generated, and what they are useful for. 



TurboTime Podcast: Part I: Compressor Maps with the Myth Busters 

During this episode of the TurboTime podcast, we discuss digital ecosystems with Jim Nyenhuis, the Performance Consultant at Emerson’s Power and Water Solutions Business. We focus on software, including AI-based software, detection and monitoring technologies, software’s influence on a turbomachine’s life, as well as cybersecurity and potential risks that power plants are exposed to.

Q: How does a digital ecosystem improve operational efficiency, plant safety, etc.?

 Digital technologies allow us to address all those issues. We work with customers to understand what operational efficiency means to them based on their objectives. Plant safety is without question built into everything we do. We want to understand and leverage what the underlying technology can tell us and let that information feed up through the digital ecosystem—how do we understand what's working well at the plant level, how do we identify if there are control problems or if individual pieces of equipment are having issues? A lot of that information is lying within the automation infrastructure, and I don't think we've leveraged that to the degree we want to. We find many customers do not understand the performance characteristics of their closed-loop controls or areas to drive additional improvement, efficiencies, etc.

Performance and control management is another big area that we look at. Our information, such as the automation system, will oftentimes track what operators are doing within the system. In the past, that information was stored in text-based logs, but there's a lot of valuable information stored in those log files that if we expose that information, we can understand how operators are interfacing with the system during different periods of operation, be it startup, shut down, various operating modes, etc., and based on that we can determine where operators are spending a lot of their time.

In this episode of the TurboTime podcast, we talk about digital ecosystems, including AI-based software, cybersecurity, and more with Jim Nyenhuis from Emerson. 

TurboTime Podcast: Software & Cybersecurity with Emerson 

In this episode of the TurboTime podcast, James Montgomery and John Mason of Rolls-Royce talk about micro-reactors. Microreactors are compact, portable reactors that produce thermal energy, which can be used as heat or converted to electric power. Micro-reactors can be quickly deployed and installed, and when they utilize a responsive design concept, they can prevent overheating and require fewer components, fewer operators, and less maintenance.

Montgomery is the Chief Design Engineer for the Rolls-Royce novel nuclear team in the United Kingdom. He is responsible for the design of the overall micro-reactor plant. Mason is a Systems Design and Integration Technical Specialist working within the Novel Concepts team in Bristol within Future Programs. His responsibilities are around the power-conversion system that goes with micro-reactors—i.e., the turbomachinery that takes heat from the reactor and converts it into usable electrical power.

“Micro-reactors are very small scale, in the range of 1 MW - 10 MW electrical, and that’s compared to a typical grid-supplying power plant that's in the gigawatt range and also with the new generation of small modular reactors that are in the 1/2 GW range, so we're much smaller than that,” Montgomery explained. “We have two potential applications for the microtechnology we're working on in the United Kingdom: The first one is the terrestrial variant for supplying power to different applications on Earth; and the second is the space micro-reactor that has potential applications for the lunar base as part of the space program and, in the longer term, for power and propulsion applications on satellite and deep-space missions.”

Montgomery also explained the process of designing a micro-reactor: “At Rolls Royce, we have a great pedigree in designing complex systems like this, so the first step in that process is to work with potential end users to understand the user requirements and use cases where we can get value from the technology. Then we'll work through the process of preliminary design and size of the plant, understanding what the technology can do and where the technology gaps might be. That then launches us into a technology program to acquire the technologies we need.

“The microreactor plant is really interesting from that point of view because it's genuinely a new product for us at Rolls-Royce as with the rest of the industry,” Montgomery continued. “So, we've pieced together some of our pedigree from the nuclear side and the turbomachinery side that we have developed over many years for aerospace and industrial applications.”

In this episode of the TurboTime podcast, James Montgomery and John Mason of Rolls-Royce talk about micro-reactors.

In part two of this episode on digital twins, Myth Busters Klaus Brun and Rainer Kurz expand on the applications of a digital twin, its advantages and limitations, and the integration of AI in the platform.

Rainer Kurz highlighted a best-use scenario for digital twin technology: “If you have large fleets of reasonably similar machines, it’s much easier to set up a system of digital twins for condition-based maintenance where you get constant data flow and are able to advise the users on maintenance decisions. It’s actually a very powerful tool.” 

Brun added his thoughts on modern digital twin integration: “The combination of a digital twin with other technologies such as fleet monitoring, forecasting, and condition-based monitoring provides an opportunity to improve the operation of the machine.”

Brun said he’s seen promising work being done with AI. “I recently read a doctoral dissertation from a university in Europe, which was interesting because AI was able to parse the data and come up with some intelligent forecasting of failures and at least, theoretically, improved the availability of the machine,” he said. “Learning algorithms have been around for about 30 years or so, but they’ve really only gotten good in the last five years. Now we’re starting to see AI make inroads into more complex things like compressors, gas turbines, steam turbines, plants, etc. I have no doubt that we’ll see more of this and better AI, but at this point in time it doesn’t replace any operator and it’s in its infancy.”

Kurz continued the discussion on AI applications: “One of the big promises of AI is guiding an operator through the system he’s operating. For example, helping the right warnings to show up at the correct time and giving him the right information. There is not AI that simulates complex systems, it simply augments the capability of the human to help make decisions.”

In part two of this two-part episode, Myth Busters Klaus Brun and Rainer Kurz cover the applications of digital twin technology, its advantages and limitations, and pairing it with AI.

TurboTime Podcast: Part 2: Applications/AI for Digital Twins 

In part one of the TurboTime podcast on digital twins, Klaus Brun and Rainer Kurz offer a simplistic description to provide a background on the technology. “At its very basic form, it’s a numerical representation of what a piece of equipment does," Brun said. "Of course, with the availability of far more data from our equipment and the availability of things like more computing power and potentially some forms of artificial intelligence, you can make these things really powerful. Ultimately, you build a model on how you think the equipment performs and then use data to determine if it really does what it’s supposed to do.

“The idea is to look at the machine and what it’s doing in the field, look at what the digital twin says it should be doing, and then compare to see if something’s gone wrong,” he continued. “Ultimately, this digital twin is supposed to simulate what the machine is doing, it should get input from the machine, it should correct itself over time—so if the machine is degrading over time, then hopefully the digital twin will figure that out.”

Regarding digital twin technology for gas turbine models, Rainer said: “For example, if you have a mechanical and thermodynamic model of a gas turbine where you can determine temperatures at various points of the machine, based on measured data and certain operating conditions, then you can simulate the remaining life of certain components that are limited by stress factors.”

Rainer continued to offer insight on the varying digital twin models within the turbomachinery industry and the importance of good data: “The tendency is moving away from physics-based toward more statistical, AI-based, big data model now. It is really important to understand that unless you have a lot of data and it’s good data, you have nothing.” 

Brun added: “That’s actually one of the big challenges specific to big data that we as engineers face. Data scientists will tell you to give them enough data and they’ll find all the correlations you want, but then you realize correlation and causation are often two very different things.”

In part one of this two-part episode, Myth Busters Klaus Brun and Rainer Kurz provide a background on digital twin technology and how it impacts the turbomachinery industry.

At Turbo Expo 2025, Antonio Escamilla Perejon, Client Relationship Manager at ETN Global, sat down with 

rnational to discuss how micro-gas turbines are adapting to alternative fuels like hydrogen, their role in the push to decarbonize, and their inherent built-in features such as fuel flexibility and modularity.

ETN Global says micro gas turbines are improving due to advances in heat recovery, fuel flexibility

Micro Gas Turbine Advancements and Market Dynamics

TURBO: How are micro-gas turbines adapting to alternative fuels like hydrogen, and what's their role in the push to decarbonize?

Micro-gas turbines are well-suited to lead the transition to cleaner fuels due to their inherent fuel flexibility and modularity. We can already find some models on the market that operate with hydrogen blends, and research and development are underway to enable operation with up to 100% hydrogen and stable combustion. Regarding low NOx, we want to achieve net zero. We also need to target those hard-to-electrify industries where micro-gas turbines can be robust solutions. In this case, these sectors require both heat and power, and many times they lack grid reliability. Within ETN Global, we support hydrogen readiness through our hydrogen working group and various cross-sector collaboration projects. We believe in the unique potential of micro gas turbines as a bridging technology to achieve net zero. Additionally, some ETN Global members are using micro-gas turbines to develop and validate concepts such as hydrogen combustion and carbon capture and sequestration. These smaller systems allow for faster iterations, lower experimental costs, and serve as a foundation for developing concepts that can later be scaled for larger gas turbines. This bottom-up approach can really accelerate the energy transition.

TURBO: What are your clients' top priorities regarding micro-gas turbines, and how is ETN Global directly supporting these needs?

: End users are primarily focused on reliability, lifecycle costs, fuel flexibility, and a clear path toward lower-carbon operations. There is a bit of a concern about market fragmentation, as there is a need to standardize interfaces, build up trust, and scale deployments. ETN Global is addressing this by setting up a collaborative and competitive environment that accelerates shared learning and supports technology development. ETN Global acts as a neutral facilitator connecting OEMs, operators, suppliers, research institutions, and policymakers to identify barriers and drive innovations. Our support for the European Micro-Gas Turbine Energy Forum can help amplify the visibility and momentum of the micro-gas turbine.

to read ETN Global's Turbo Expo session on micro-gas turbines.

Antonio Perejon of ETN Global says micro gas turbines are improving.

TURBO: What key technological advancements are currently driving micro-gas turbine adoption globally?

 Recent developments in heat recovery systems, fuel-flexible combustion, and digital control systems are significantly improving the performance and appeal of micro-gas turbines. Hot temperature materials and more robust coatings are reducing maintenance and increasing equipment lifetime. While more advanced control systems enable autonomous operations and easy integration, some manufacturers are choosing more complex architectures, such as two- and three-spool configurations, which enable greater operational flexibility and allow turbines to operate more efficiently across burning load conditions, which increases the part load efficiency and supports easier integration with dynamic energy systems.

With ETN Global’s Energy Integration Working Group, we are fostering continuous collaborations to support these developments, especially around decarbonized fuel compatibility and system integration. The sector is advancing, but scale remains a barrier. Adoption is still hindered by low commercial volumes and a need for a broader market pool.

TURBO: What are the primary global drivers for the micro-gas turbine market growth?

 Market trends arise from a growing demand for decentralized and resilient energy systems. Moreover, there is a need for combined heat and power, which offers continuous power, low emissions, and minimal noise, along with the potential for integration with low-carbon fuels. Unlike larger gas turbines, the micro gas turbine market remains small and faces intense competition from technologies such as fuel cells, internal combustion engines, and even solar photovoltaics. The reasons for this include the battery engine system, which typically benefits from greater visibility and funding within ET and globally. We are supporting and fostering this through our technical platforms and at the European Micro Gas Turbines Energy Forum, which we are co-sharing. This year marks the first signs, and we will host the discovery in Brussels.

Antonio Perejon of ETN Global says micro-gas turbines are improving due to advances in heat recovery, fuel flexibility, and digital controls, but market adoption still faces challenges.

Micro-Gas Turbine Advancements and Market Dynamics

At Turbo Expo 2025, Tim Allison, Director of R&D in the Machinery Department at the Southwest Research Institute (SwRI), sat down with 

 power cycle research and development, including the STEP Demo pilot plant.

Tim Allison of SwRI shares the biggest remaining hurdles for widespread sCO2 turbomachinery commercialization and the most promising energy storage solutions.

SWRI Shares Biggest Hurdles for Widespread sCO2

 power cycle research and development, including the STEP Demo pilot plant. What are the biggest remaining hurdles for widespread sCO

 turbomachinery commercialization, and how is SwRI addressing them?

The Southwest Research Institute is the host site for the STEP Demo pilot plant, which was successfully commissioned late last year, running a simple-recuperated cycle with a turbine inlet temperature of 500° C. Part of that operation was to run the turbine as well as the main compressor, which is a centrifugal compressor. We were able to run those right at predicted performance for the operating condition that we were in. We encountered some growing pains associated with handling the high pressures as well as the high temperatures in the turbine, which was a design factor, but we found that there are no real technology gaps there. As long as you account for the pressures and densities associated with those machines, they do not have any fundamental technology problems.

Toward commercialization, we see a need for increasing the temperature. We are scoped to run the step demo at 700° C later this year; we also see a need to increase the number of operating hours. And then there's a lot of commercial interest in developing solutions that will fast ramp the machinery or incorporate hermetic machinery designs to minimize the CO

What are the most promising turbomachinery-based energy storage solutions SwRI is exploring, and what unique challenges do they present?

We developed a software tool to analyze energy storage systems to help answer that question. What we found is that when simulating various renewable resources, market economics, and electricity prices for your area, the most technically and economically viable solution varies based on those inputs. We are exploring a broad range of energy storage technologies that could be suitable for different applications. These technologies include options like pumped thermal energy storage, liquid air energy storage, hydrogen, geomechanical storage, and other thermal storage mechanisms that are coupled to turbo machinery. Currently, we observe strong trends toward thermal energy storage systems that can either direct heat toward an industrial process or direct thermal energy to a heat engine for conversion back to electricity. This flexibility for dual use is quite appealing for commercialization. Additionally, we are noticing interest in hybrid energy storage systems that incorporate thermal energy storage linked to existing gas or steam turbines. The idea of coupling to those existing resources enhances retrofit economics and increases the utilization of the capital asset, making them quite promising.
