Abstract : The laminar compressible boundary layer in chemical equilibrium is analyzed to show the effect of emission of radiation by the boundary layer on solutions of the energy equation and on the resulting heat transfer. Solutions are obtainedAT ONE FLIGHT CONDITION, BUT FOR SEVERAL NOSE RADII, IN A REGIME WHERE ABSORPTION IS NEGLIGIBLE. The consequent effects on heat transfer and boundary-layer thickness are determined. The concept of a separate boundary layer and shock layer is discussed in the light of the results obtained.
