Abstract

The present paper aims at a calculation of temperature field in the compressible turbulent boundary layer over a flat plate in a high velocity flow. The energy equation is solved with the aid of the three scaling functions which are proposed by Coles for an analysis of the velocity field. The scaling functions relate the compressible flow field to an incompressible one. The 1/n-th power profile and the Spalding formula are employed as the basical incompressible velocity profile. This analysis is applicable not only for an adiabatic or an isothermal surface but for nonisothermal surfaces.
