An improved integral method for compressible turbulent boundary layers
Abstract
A dissipation integral type method has been developed for compressible turbulent layers with pressure gradient and heat transfer. The basic idea of the proposed method is to use the integral version of the transport equation for the turbulent energy. By introducing modeling assumptions and the CroccoBusemann integral, this integral transport equation can be transformed into an integral equation for a shape parameter of the Reynolds shear stress profile. Thus, three instead of two integral relations have to be solved simultaneously: one for the thickness parameter, a second one for the shape parameter of the velocity profile, and a third one for the shape parameter of the Reynolds shear stress profile. The last equation replaces empirical relationships for the dissipation integral. Numerical results are found to be in good agreement with experiment.
