Abstract:

A method has been developed for treating the three-dimensional compressible laminar boundary-layer equations for a right circular cone at angle of attack in supersonic and hypersonic flow. Swallowing by the boundary layer of the inviscid entropy layer streamline swallowing has been treated by means of a mass-flow balance between the inviscid and viscous flowfields. The boundary- layer equations between the inviscid and viscous flowfields. The boundary-layer equations were developed in a general Crocco-variables form. A finite- difference technique was formulated for solving the governing equations and treating the streamline-swallowing phenomenon. The resulting second-order difference equations are solved in an iteration scheme.
