Laboratory Testing

Concepts NREC operates extensive performance testing facilities to validate the operating specifications and design objectives of pumps, compressors, and turbines. Each of these facilities can adapt to a wide variety of requirements for evaluating both scale-model prototypes and full-dimension turbomachinery components and complete machines.

Extensive Testing Capabilities

Concepts NREC's test laboratories contain instrumentation from classical pneumatic and thermal probes and traverses to more sophisticated hot-wire/hot-film and laser anemometers, high frequency pressure transducers, and proximity probes. Data acquisition systems, laboratory software, flow traversing equipment, instrumentation devices (probes), and calibration services for various pressure and temperature probes are all available.

Flow, Pressure, Temperature, and Force Measurements

Concepts NREC has developed unique rigs for determining the forces and moments on rotating impellers, bearings, seals, couplings, and other components. These rigs provide a full suite of flow, pressure, temperature, and force measurements for an accurate characterization of performance and rotordynamic characteristics. Magnetic bearings precisely control the position and vibration of the component being tested, while documenting the fluid forces created either by movement or the operating load.  Additionally, Concepts NREC has the capabilities for both static impeller modal testing and dynamic strain gage telemetry for mechanical assessment of compressors and turbines.

Using automated data-acquisition and reduction routines, Concepts NREC’s central data-acquisition facility can be configured to sequentially scan up to 144 pressures, 40 electrical signals, and 50 temperatures. This facility can acquire and analyze dynamic pressure signals and vibration sensors, as well as the scanned steady-state data. The laboratory data files that are generated can be used directly by other codes to process the traverse and impeller cover static pressure data. The data can also be automatically processed through Concepts NREC’s 1D meanline codes such as COMPAL® to generate full performance maps and detailed component aerodynamic performance parameters.

I came to the realization that we needed some objective insight.

We were working well with the OEM but even with our combined efforts, we were struggling to get a critical compressor to pass performance on their test stand. Although I'd never directly done business with Concepts NREC I was familiar with them and their capability so I chose to contact them when I came to the realization that we needed some objective insight. Concepts NREC fielded my cold call and immediately engaged their expertise in a complex problem that was also challenged by schedule constraints. They provided increased understanding of an already complex CFD which resulted in increased confidence that the proposed solution would succeed on the next test stand attempt (which it did!). We are pleased to have had the help of Concepts NREC and now have a well-performing compressor in our process.”

Compressor Design : Axial, Mixed, or Radial?

With so many papers out there, I like to pass the word along when a particularly good one comes my way. My favorite paper for 2021 was titled “SELECTING A COMPRESSOR MERIDIONAL TOPOLOGY: AXIAL, MIXED, RADIAL”. A good paper doesn’t just show how clever the authors are (though they clearly are) but it teaches the reader something that they can use in their trade. The lead authors of the paper were appropriately named Smyth and Miller. Not the Smith of the acclaimed Smith chart but clearly inspired by his similar namesake. The two hail from the Whittle Lab at the University of Cambridge.

Which Type of Turbomachinery is Aerodynamically Easier to Design, a Compressor or Turbine?
by Daniel V. Hinch, Corporate VP Sales and Marketing, Concepts NREC
In the world of aerodynamics, there are several branches and sub-branches of different types of aerodynamics. In the big picture the field of aerodynamics can be broken down into external and internal aerodynamics.   External aerodynamics is thought of external flow around an isolated body, with the typical example being flow around an aircraft wing section, or perhaps around an automobile. There is typically a far field ambient condition, with an isolated body moving through the field (or you can view it as the fluid moving over the body). Internal aerodynamics is thought of as a flow moving through some confined space or passage, with a prime example being flow through turbomachinery, such as a compressor or turbine. There are other ways to classify aerodynamic flow, such as subsonic flow (Mach No. <0.8, including low Mach No. incompressible flow, say Mach No. <0.3), transonic flow (around Mach No. = 1, say 0.8 to 1.2), supersonic flow (Mach No. > 1.2), and even hypersonic flow (Mach No. >5). Turbomachinery design encompasses the first three types of flow regimes, subsonic through supersonic. So in general, turbomachinery aerodynamics is predominately internal flow, over a range of Mach Numbers.
