Advanced Diffuser & Volute Design Consortium

The seventh phase of the Advanced Centrifugal Pump and Compressor Consortium for Diffuser & Volute Design is focused on improving diffuser designs to exceed 80% energy recovery. Work is underway but there is still time to join. The program builds upon earlier consortium research and Concepts NREC’s own long history of innovative diffuser and volute design. The current Consortium phase consists of leading international sponsors from across the global turbomachinery industry.

“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?
by Mark R. Anderson, CTO of Concepts NREC
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.
