Paper Abstract

The injection and mixing of iodine vapor into a duct flow has been investigated experimentally and numerically. Laser-induced fluorescence has been used to visualize the progress of spreading of the iodine and its distribution homogeneity along the duct. Several injection methods, typical flow pressures for oxygen-iodine lasers, and various molar flux ratios have been examined to find the most favorable conditions for the mixing in supersonic lasers. A one-dimensional gasdynamic and kinetic computer model taking into account a zone of bulk type mixing with variable extension was used for estimating the influence of the mixing speed on the rate of dissociation and on the performance parameters of a supersonic oxygen-iodine laser.
