Hello,

I am currently trying to select a code to model hypersonic flow, capturing the correct real gas effects.

Any reccomendations/comments on Fluent, GASP, CFX, or CFD++.

Thank you.

Real gas effects mean different things to different people. For some, it means that chemical kinetics, or air dissociation are taken into acount. For others, it means chemical kinetics + non equilibrium thermodynamics. For others still, it means a gas with the density of a fluid, the supercritical properties regime. GASP seems to be the most accepted commerical code for hypersonic stuff. It is pretty reasonably priced, as far as I remember.

I use CFD-Fastran. It has all the features of GASP & NASA's overflow combined. The website is www.cfdrc.com
