Turbochargers

Advanced casing treatments.  Twin stage designs.  Variable geometries. vtg_1

As a turbocharger designer, your quest for better low end response, fuel economy and emissions has pushed you to the limits of conventional aero design.  

This demands CFD that's up to the task.  CFD that delivers a new level of insight to the adverse flow phenomena impacting boost, efficiency and operating range.  CFD with the analytical horsepower to support advanced impeller, variable geometry and casing treatment designs. And CFD that allows you to innovate with speed and confidence.

Here's how we can help:

radialimpellerHassle-free impeller meshing

ADS takes the frustration and wasted cycles out of turbocharger impeller 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 under a minute.

Accurate capture of turbocharger flow physics

As 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 calibration-free insights you can rely on to assess boost, operating range and efficiency.

Single row and multistage 3D steady analyses accurately capture speedline trends near surge and choke.  And time accurate studies 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 using our advanced workflows, returning precious cycles back for design optimization or faster time to market. ADS also finally makes unsteady analysis practical, delivering order of magnitude speedups to allow you to better anticipate high cycle fatigue and rotating stall within tight design windows.

ADS CFD analysis capabilities include compressor wheel and diffuser blade design, turbine wheel and inlet guide vane design, flow angle studies for variable geometry designs, casing treatment models to optimize ported shroud placement, and blade row interaction analysis to mitigate adverse IGV-impeller or impeller-difuser interaction effects.

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?
