Abstract: Four multiple-scale turbulence models and two baseline models are applied to simulate the flows over a series of two-dimensional compression corners. Comparisons are made and assessment of the models are performed withdiscussions of compressibility and its effect on nonequilibrium energy transfer. It’s shown that the treatment of multiple scaling is efficient and potential.
