Experimental Investigation of a Supersonic Shear Layer with Slot Injection of Helium

We focuse on mixing in a shear layer developed from helium slot injection into a parallel supersonic airstream and compare the results to those of previous slot-injection tests. In addition to short-duration schlieren and shadowgraph photography, concentration, pitot, cone-static, and stagnation temperature measurements are presented to document the development of the mixing layer.
