Contribution to the Study of Supersonic Laminar Separation: Utilization and Improvements in Integral Methods of Calculation

摘要

The calculation of the phenomena associated with supersonic laminar separation was studied by coupling the solution of the equations of the ideal fluid and the boundary layer equations expressed in integral form. The definition of similar profiles was approximated by a simple analytic representation and the implementation of a second order boundary layer formulation. Le Balleur's numerical calculation method was adapted to laminar flows, and applied to the study of separation and reattachment on a compression ramp or due to a shock wave reflection. Some three parameter velocity profiles are determined which are able to take account of the effects of the laminar sub layer, which are then used in a three moment integral method.
