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.

TurboTime Podcast: Part 1: What is a Digital Twin? 

In this episode of the TurboTime podcast, Dr. Mike Shepard, Vice President of Aerospace and Defense at 3D Systems, discusses additive manufacturing, including its background as a fabrication technique in the turbomachinery industry, the role of data, as well as the various types of additive manufacturing. Dr. Shepard also addresses the advantages and disadvantages of this 3D printing technology, including size constraints, dimensional tolerance, etc., and advancements he sees happening in the near future.

"The adoption of additive manufacturing has really been growing in the turbomachinery industry,” Dr. Shepard said. “I'd say that's true in a couple of different ways—not just in the new-build environment where you're getting new construction and new designs, but it's also really important in the refit and aftermarket environment—parts, etc. And there are a lot of different reasons, right? You get design flexibility more than traditional methods. However, it's not going to replace things like CNC, but it's going to powerfully complement them. You also get very complicated geometries, which are possible now. And it's easy to incorporate extra complexity like cooling channels for fluid flow. You can also utilize it to combine a bunch of parts into one, which is super advantageous. We've seen examples where people were able to go from 200 components sometimes into one, and you can also iterate very quickly. So, these are the types of advantages that designers really love, On the back end, in the aftermarket/spare parts, it can potentially cut down on your lead time. I think a lot of the people who are listening to the podcast have probably had that experience—where you're waiting a year for a part sometimes, right? So with the additive manufacturing technologies that we have now, you can sometimes get that core metal part in a few days. So that kind of design flexibility and really tightening up your supply chain means that people are driven to pick up additive manufacturing technologies."

Shepard closed out the show with a forecast on the future of additive manufacturing technology: "I think we're going to see a lot of improvements in terms of the throughput of the processes and the economy of the processes. I'm really excited about the work that people are doing in metallurgy; there are these new computational methods you can use to discover new alloys, and you’ll see this more and more."
