Abstract : It is shown below that for plane, steady flows even with entropy and vorticity gradients it is sometimes possible to have simple wave solutions in the form of the ordinary Prandtl-Meyer expansion. The essential conditions to guarantee the result are that the Mach number be supersonic and constant and the pressure be constant in the region upstream of the expansion zone. For simplicity, the discussion is carried out for a perfect gas.
