Several new similarity solutions are presented for the laminar compressible boundary layer with reverse flow for Prandtl numbers of 1.0 and 0.723. New solutions without reverse flow are presented for Prandtl number equal 0.723. Wall‐to‐stagnation temperature ratios from 0 to 2 are considered. These solutions quantitatively show the effects of pressure gradient, and wall heat transfer on the wall shearing stress and enthalpy gradient.
