Centrifugal Compressors

As a centrifugal compressor designer, you've helped to power a wide variety of industrial markets. While centrifugal compressors have proven robust for low-medium compression ratio applications, achieving high performance remains a challenge given the complexity of the geometry and flow field.

This demands CFD that's up to the task.  CFD that reliably grids complex impeller-diffuser geometries.  CFD that accurately captures time-accurate flow phenomena affecting performance and durability. And CFD that allows you to quickly iterate and optimize within tight design windows.

Here's how we can help:

Hassle-free impeller meshingradialimpeller

ADS takes the frustration and wasted cycles out of centrifugal compressor meshing. Built with radial impellers in mind, our mesh generator Wand features automated multi-splitter placement, support for constant radius cut trailing edges, and variable clearance gaps that begin radially and end axially.  Irritating mesh skew and folding problems are minimized using an advanced OHH mesh topology and visibility to clearance loss is enhanced through novel clearance meshing techniques.

Better yet, setup is easy, repeatable and fast, with most meshes generated in minutes.

Accurate capture of compressor flow physics

centrifugalAs the old adage goes, you can't fix what you can't see.  Rooted in decades of aerospace-class compressor and turbine application, the ADS solver Leo delivers flow insights you can rely on to consistently discern design improvements from design mistakes. Time accurate studies against single or multi-stage compressors are handled with ease and high fidelity, revealing key insights about the source of loss and durability issues in your design.

Design time application

clockCount on ADS to turn around your aero analysis in timeframes suitable for design. Speedlines that routinely take days to generate can be completed in hours, returning precious cycles back for design optimization or faster time to market. ADS also finally makes unsteady analysis practical, delivering order of magnitude speedups that allow you to better anticipate high cycle fatigue, rotating stall and/or surge within tight design windows.

Easy integration into design optimization loop

Converge quickly to a final design candidate by integrating these capabilities into a design optimization loop.  All ADS CFD components can be easily integrated into your design system through the use of text-based setup files and command line executables.

Makes sense.  Now what?
