Abstract:

The report summarizes the main results and conclusions obtained during the contract period in two studies, both aimed at understanding the instability mechanisms in reacting flows. In one study, both theoretical and experimental work is conducted to determine the fluid-dynamic and chemical-kinetic mechanisms by which instabilities are triggered in flows around spherical, cylindrical and conical projectiles fired at supersonic speeds into reactive gaseous media as well as their effects on heat-release rates and approach to chemical equilibrium in the shock layer and inviscid wake.
