Abstract : A study was made of a two layered model of a compressed turbulent boundary layer with heat exchange. A temperature profile was determined from the Crocco integral; for the velocity profile in the turbulent part of the layer a Van-Drist profile was used. The distinguishing feature of the solution is dependence of the dimensionless width of the laminar sub-layer on the temperature factor and the Mach number. Results of the calculations are compared with experiments on friction and heat exchange.
