Chemical Laser Flow Simulation and Mixing Studies Using Holographic Flow Visualization Techniques

Abstract

This report is a summary of work directed toward an understanding of mixing processes in the reaction cavity of a chemical laser device. Holographic optical techniques are used to visualize the flow of gases exiting from an array of supersonic nozzles in a cold flow simulation of the chemical laser. The reconstructed holograms are used to evaluate the mixing process as a function of thermodynamic parameters, flow obstructions, and mass injection mechanisms. Analysis of the mixing is discussed and related to the flow conditions illustrated by shadowgrams, schlieren, and interferograms. Some conclusions are drawn with respect to factors that affect the mixing process.
