Mixing investigation of supersonic hydrogen and fluorine flows

Experimental data from two shock tube/shock tunnel facilities capable of simulating the mixing zone regions 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 sonic holes into a supersonic fluorine-carrying stream; the other simulates the parallel shear layer mixing developed between a supersonic fluorine-carrying stream and an adjacent supersonic hydrogen-carrying stream. A theoretical model of the turbulent chemically reactive mixing zone has been shown to provide remarkably good agreement with the experimental results for conditions where the mixing zones are turbulent.
