Abstract : A finite differences solution utilizing an explicit scheme is presented for an initial value problem in an inhomogeneous compressible laminary boundary layer. The method is to be employed in the determination of velocity, temperature, and concentration profiles in the boundary layer; and heat transfer and shear distributions on the wall. The program (written for an IBM 7094 computer) is designed to accomodate either constant or variable transport properties. Diffusion coefficients used correspond to a binary mixture and consequently applications to inhomogeneous cases are restricted to either an arbitrary binary mixture or to a multicomponent mixture the constituents of which have similar diffusion properties.
