Computation of flow past high speed vehicles requires the use of a reliable turbulence model.Unfortunately, most of the turbulence models are developed for incompressible flows.Application of these models directly to high speed boundary layers with large density gradients can Rompers lead to significant errors in prediction of skin friction.Several
