Abstract:
A model for the study of viscous inviscid interactions is presented. The boundary layer equations are solved by means of an implicit finite difference scheme the supersonic portion of the flow is calculated by characteristics including viscous terms, and the two sections of the flow matched. The possibility of a non-zero normal pressure gradient in the boundary layer is taken into account by the analysis. A shock point calculation which includes the effects of viscosity behind the shock is presented. The method is applied to a two-dimensional blunt body in hypersonic flight, and the significance of the model for high curvature and low Reynolds number conditions is discussed. A listing of the computer program which generated these results is included in the report. Author
