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.

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. 

TurboTime Podcast: Remote Monitoring with EthosEnergy

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 

In this episode of the TurboTime Podcast, we talk with Giuseppe Tilocca, Scientific Officer at ETN Global, a non-profit member association in the gas turbine technology space. ETN Global’s recent global report, 

Decentralized Energy Systems: Toward Carbon-Neutral Energy Solutions for Gas Turbines

, compares decentralized systems to centralized heat and power units and highlights its advantages—including modularity, the possibility to exploit waste heat avoiding energy transmission losses, and reducing energy distribution costs. Tilocca reviews these advantages in detail, as well as trends and emerging market opportunities, and he dives into gas turbines and how they fit into decentralized energy systems.

“Considering this specific report, we all know that the energy sector is transforming very quickly, and it's mainly driven by the increasingly high share of renewable energy sources,” Ticolla said. “In this scenario, which is dominated by variable sources whose daily, weekly, and seasonal flexibility are set to go dramatically, to meet the system requirements while accomplishing the ambitious decarbonization goals, we need to support traditional centralized generation with a mix of the centralized components.”

So, how does ETN Global define decentralized energy systems, and what are their advantages?

“Historically, we established centralized energy systems, meaning large plants located far from consumers,” Tilocca explained. “The reason behind it is merely economy of scale and efficiency, so it is cheaper to have one big plant than many small ones; however, with the increasing integration of variable renewable energy sources, which are inherently decentralized, we now need to adapt our infrastructure and incorporate technologies that are traditionally used for centralized energy. By definition, a decentralized energy system is located close to the consumption nodes—so on the end user side of the network—and therefore it's connected to the distribution grid rather than the transmission grid. The advantages of a decentralized energy system are mainly modularity, the possibility of exploiting waste heat, and a positive contribution to stability. In particular, one of the main advantages of being close to consumption nodes is avoiding transmission and distribution losses and also costs compared to centralized generation. Centralized energy systems are pivotal in meeting the pillars of the energy trilemma, which stress the principles of affordability, security, and climate neutrality and hence it aligns with the requirements for the transition toward 2030 but also 2040 and 2050.”

ETN Global’s Scientific Officer, Giuseppe Tilocca, talks about the association’s recent report on decentralized energy systems—their advantages and challenges, trends, and where and how gas turbines fit in.  

TurboTime Podcast: Decentralized Energy Systems with ETN Global 

In this episode of the TurboTime Podcast, the Myth Busters discusses the role of turbomachinery in energy transport and storage, including how gas turbines maximize energy density. They dive into various forms of energy storage—including batteries, hydrogen, and mechanical and thermal energy—for various energy sources such as wind, solar, fossil fuels, etc., and more.

During the energy transport and conversion processes, for example in the case of hydrogen, there are significant energy losses. The lowest losses are with coal, then oil and fossil fuels. As a result of these losses, “Hydrogen is a viable solution for storage, but it’s not a great solution to power a large-scale electric power plant by itself,” Kurz said.

Really, energy comes down to sustainability, affordability, and sustainability of supply – and in this equation, renewables are typically intermittent and not a reliable full-time source of energy.

So where does turbomachinery fit into all of this?

“From a turbomachinery perspective, if you exclude electric—because as Rainer said, it's not always applicable, as you can’t transport energy from Venezuela to Florida along an electric line—then you have to convert your energy stored material, be it natural gas, oil, coal, or from an alternative source then you have to convert it into hydrogen or ammonia or something else, and then transport it,” Brun explained. “All these convergent processes utilize turbomachinery. We have maybe 100 years of experience transporting oil in pipelines and ships and trucks and that involves a lot of pumping—we're very good at pumping – it’s very efficient. We also have about a similar amount of time compressing natural gas, which over the last 40 - 50 years we've used a lot more centrifugal compressors for transporting natural gas. Now we're running into the challenge of sustainable alternative energies where basically you're saying, ‘OK, I'm going to take my wind and solar electric and convert them to let's say hydrogen or ammonia or dimethyl ether or methanol—there are a lot of fluids that you can make from electricity that are energy carriers—but then they have to be transported. Hydrogen is the lightest gas (We had a previous podcast where we talked about the challenges of 

). Similarly, ammonia is a liquid that has to be transported at slightly refrigerated temperatures, and it brings its own challenges because it's highly poisonous and very corrosive to a lot of materials. Dimethyl ether is not that hard to transport—it’s similar to diesel—but it's very expensive to make. Methanol is also highly poisonous. So there are a lot of other challenges that you now face with these energy carriers that you worry about when transporting your original form of energy to the end user.”

Klaus Brun and Rainer Kurz dial into energy storage and transport—why they are necessary, how turbomachinery fits into these processes, and more.

This episode of the TurboTime podcast dives into carbon capture and storage (CCS) with Spencer Schecht, the Senior Business Development Lead at the Global CCS Institute. We discuss how these facilities are at an all-time high, the role of carbon capture networks and hubs, and some of the challenges and hurdles it’s facing.

, said that CCS has ramped up to an all-time high— a 102% increase in scheduled deployments since 2022—due to supportive and enabling policy, as CCS is becoming a more prominent feature of public policy.

“At a high level, we need CCS and CO2 removal to meet our climate targets to achieve climate neutrality,” Schecht said. “So, while we require an all-of-the-above portfolio of climate technologies and solutions, it is the versatility of CCS—the fact that it enables both emissions mitigation and removal—that makes it such a unique and important resource in our climate toolkit. For example, CCS can be applied across emissions-intensive industries, including hard-to-abate sectors such as steel, cement, chemical production, and power production, to achieve decarbonization that is not otherwise technically nor economically possible. This enables the reduction of low-carbon hydrogen, and it can also be retrofitted on fossil-fuel power plants or incorporated in the design of new power plants providing baseload low-carbon dispatchable electricity. And when combined with bioenergy or direct air capture, with permanent geologic storage, CCS is an enabler of delivering negative emissions, and we need negative emissions to scale massively in the years ahead. This lays out a very clear picture that CCS and CO2 removal must scale up to gigatons, which is billions of tons per year, to achieve our climate targets.”

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, the Myth Busters, Klaus Brun, the Director of R&D at Elliott Group, and Rainer Kurz, a recent retiree from Manager of Gas Compressor Engineering at Solar Turbines, discuss turbomachinery codes and standards. The two differentiate codes versus standards, which are important for turbomachinery, and what to do if an operator or manufacturer disagrees with a standard.

Brun broke down the four components: standards, codes, specifications, and guidelines. “A standard is somewhat of a generic requirement; you can almost call it the minimum requirement that industry associations agree on for a piece of equipment,” he said. “There's a lot of gray area between here. Next are specifications—they are often related to a specific customer—one of the major oil companies may have its own specifications, and they often tie in standards. For example, let's say Shell or Chevron has their own machinery specification, and they may refer to standards, such as American Petroleum Institute (API) 616 or the American Society of Mechanical Engineers (ASME) standards, material standards, etc. And then you get into things like codes, where the gray area becomes even bigger. But codes traditionally refer to something a little stricter. These can be test codes, where there is a process that you have to follow, and you don't deviate from this process. There are codes related to OSHA requirements or legal requirements. Codes tend to be a little more rigid, more relevant, and more richly followed. Finally, there are industry guidelines from the API and other professional societies. They give advice and guidance on how to handle testing processes, design, etc.”

Kurz stressed that standards are not legally enforceable unless included in a purchasing agreement: “What makes a standard enforceable is if a customer in the purchase specifications says ‘Thou shalt follow such and such API requirement or these ASME standards.’ And then it becomes part of the contract and enforceable” he said.

Kurz also pointed out that one purpose of codes and standards is for system integration. “If you build a refinery, there's one manufacturer who builds the compressor, then there are people who build the pressure vessels, others who build the piping, and maybe the steam turbines. So, there are a lot of different parties involved that have to come together. And one thing that these codes and standards do is create a reasonable definition of the interfaces. At the end of the day, somebody needs to integrate all that equipment.”

The Myth Busters, Klaus Brun and Rainer Kurz, discuss turbomachinery codes and standards on the TurboTime podcast.

to discuss how SwRI is advancing diagnostics and predictive maintenance to extend the life and improve the reliability of existing turbomachinery, and how decarbonization goals are influencing turbomachinery design in terms of new materials and alternative fluids like hydrogen.

: Tim Allison of SwRI shares how the institute is working to improve turbomachinery reliability and material compatibility of hydrogen and sCO2 oxy combustion

SWRI Says NPSS Turbomachinery Models Can Guide Future Preventive Maintenance to Improve Reliability  

How is SwRI advancing diagnostics and predictive maintenance to extend the life and improve the reliability of existing turbomachinery?

SWRI develops the NPSS software code. It's a numerical propulsion system simulator, which is a thermodynamic tool for modeling gas turbines or turbomachinery and power systems. That code is the industry standard for aerospace gas turbines and has paved the way toward adoption with multiple industrial turbine OEMs over the last few years, and they do actively use that code as the basis for developing digital twins for their models. The NPSS models of turbomachines can be used to track degradation and guide future preventive maintenance efforts for reliability.

We also do a lot of work solving or improving reliability by solving problems in the field. We have a staff that travels with all sorts of instrumentation for processes, as well as advanced optical measurements for vibration and rotating shafts to help diagnose issues in the field and improve reliability.

How are decarbonization goals influencing turbomachinery design at SwRI, particularly regarding new materials and alternative fluids like hydrogen?

SWRI's efforts toward decarbonization technologies are really guided by our clients, so we support a lot of their interests. Right now, we're seeing a lot of interest in technologies like hydrogen, carbon dioxide, supercritical carbon dioxide (sCO

), and industrial applications reducing carbon or effective carbon emissions. Those involve machinery technologies like hermetic machines and really high pressures and temperatures to improve power density and efficiency.

To improve those designs, we incorporate different test rigs that are designed to evaluate the material compatibility of hydrogen or sCO

 oxy combustion at elevated or actual conditions. We also have a number of component test rigs for the components that are needed to support machines in these applications. So, we have different bearing test rigs and seal test rigs that help us to develop components for hermetic machinery at high pressures or high temperatures.

Tim Allison of SwRI shares how the institute is working to improve turbomachinery reliability and material compatibility of hydrogen and sCO2 oxy combustion.
