Abstract

Abstract: In the k-ε turbulence model the effect of compressibility is generally neglected and an incompressible version of the model is used. However, with high Mach numbers results can be improved by a compressible dissipation. Main result: Correction term owing to compressibility to the turbulent dissipation rate.
