Experimental Investigation on the Effects of Chemical Heat Release in the Reacting Turbulent Plane Shear Layer.

Abstract

A chemically reacting shear layer between various gases was investigated in a new type of blow-down wind tunnel. The gas streams were inert (helium, nitrogen or argon), but carried up to 10% concentration of reactants, one being ozone and the other nitric oxide. The resulting reaction, 03 + NO yields N02 + 02, was essentially diffusion limited and spontaneous, enabling the temperature rise to be varied at will from zero up t 200 C mean. Flows of Reynolds number up to 5 x 10 to the fourth power were investigated.
