SUPERSONIC SEPARATED FLOWS OVER WEDGES AND FLARES WITH EMPHASIS ON A METHOD OF DETECTING TRANSITION.

Abstract

The investigation is a first step to the study of the effect of cross flow in laminar separation at supersonic speeds. It is related to the selection of a final axi-symmetric model. Several problems were examined: first, the effect of streamwise vortices that develop systematically in laminar reattaching flows, triggered by small irregularities in the leading edge thickness; second, the choice of the diameter of the model such that the flow resembles that on an equivalent planar body; third, the programming of Lees-Reeves theory on a 1130 IBM computer to perform a parametric study; and finally the development of a new accurate technique or criteria to ascertain that fully laminar shock wave boundary layer interactions can be obtained.
