PARALLELING an experimental program, an analysis was performed to obtain solutions for the heat transfer and flow characteristics of a two-dimensional stagnation-point flow in which air is the main stream gas and helium is injected into the boundary layer at the surface. The differential equations and boundary conditions describing the mass, momentum, and energy transport in such a boundary layer are contained in [l] and will not be repeated here. They are also identical with the boundary layer equations for flow along a surface with uniform pressure (flat plate) as given in the more easily accessible [2], with the exception that a pressure gradient term +/ax has to be added to the momentum equation and that the viscous dissipation term &au/~# has to be dropped from the energy equation. The partial differential equations were converted into total ones by a similarity transformation, and these then were put into the form of --~ 7 These studies have been supported by the U.S. Air Force, Office of Scientific Research under Contract No. AF 49(638)-X%.
