CONE CAVITY FLOW AT M = 5.3 WITH INJECTION OF LIGHT, MEDIUM AND HEAVY GASES

Abstract

The effect on the reattachment pressure and heat transfer peaks of injection of air and foreign gases into the separated region of the laminar flow over a cone cavity model was investigated at M=5.3. Injection has generally a favorable effect in reducing these peaks, light gases being more effective. A correlation factor is given to relate together the effects of various gases. A surprizing similarity is found with theoretical and experimental results for unseparated flows over porous walls. Occasionally, very high frequency flow unsteadiness was observed.
