Abstract:

Experimental data from two shock tubeshock tunnel facilities capable of simulating the operational conditions of continuous flow chemical laser devices are presented. One facility is specifically designed for reproducing the reaction mixing region developed when hydrogen is injected through various sonic ports into a supersonic fluorine carrying stream the other facility simulates the parallel shear layer mixing developed between a supersonic fluorine carrying stream and an adjacent supersonic hydrogen carrying stream. Established experimental techniques, including the Mach-Zehnder interferometer, rapid scanning infrared spectrometer, pitot pressure probes, and thermocouple temperature probes, have been employed to map flow conditions within the test section mixing layer. A theoretical model of the parallel shear flow turbulent mixing region is described and results from this model are compared with measured monochromatic fringe-shift profiles. Reasonably good agreement has been demonstrated between theoretical predictions and the experimental profiles for two widely different experimental situations.
