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

摘要

Calculations were performed on supersonic layer separation phenomena by solving coupled perfect fluid equations and integral form boundary layer equations. Three types of improvements are suggested: definition of similitude profiles approximated by a simple analytical representation and the use of a second order boundary layer formulation proposed by Crocco, adaptation of Le Balleur's numerical method and its application to separated and reattaching flow on a compression ramp or under shock wave reflection conditions; and determination of three parameter velocity profiles able to take sublaminar layers into account and their utilization in a three moment integral method as suggested by Crocco.
