Abstract

A new low Reynolds number modification to the k— ∊ model for compressible turbulent flow is presented. The modification employs the minimum number of changes to the high Reynolds number k — e model, and utilizes physically correct boundary conditions at the wall. Good agreement is obtained with experimental correlations for adiabatic and isothermal flat plate boundary layers. For a supersonic adverse pressure gradient boundary layer, good agreement is observed with the velocity and Mach number profiles. However, •he skin friction is overestimated by 20%, and signfieant differences are observed in the Reynolds stress.
