AN INVESTIGATION OF A SUPERSONIC SURFACE JET-HYPERSONIC FLOW INTERACTION WITH AXIAL SYMMETRY.
Abstract
The complex interaction between a supersonic air jet from a slot with a hypersonic flow of air over a surface was investigated experimentally. The conditions were such that the boundary layer was fully turbulent and both injectant and free stream, at different temperatures, could be considered to be perfect gases. The design of the experiment followed a consideration of the governing non-dimensional groups. From physical arguments, the parameters considered to control major changes in the interaction structure, the angle of the jet to the surface, and the jet to free stream pressure ratio, were selected for study. The experiment was carried out at M = 6 using a 5 deg cone with a circumferential slot. Optical observations were made and surface pressures were measured. Impact pressure and stagnation temperature surveys were recorded and reduced to obtain mass flux and other flow profiles using digital computer techniques. (Author)
