Abstract

To investigate development of an air-hydrogen supersonic shear layer and distribution of hydrogen concentration, a hydrogen jet was injected into a cold air supersonic free-stream in a parallel direction. The free stream Mach number was 1.81, Using a catalytic reaction on a platinum wire, heat release due to catalytic reaction, a heat transfer coefficient and hydrogen concentration were measured. It was shown that parallel injection was found to affect on mixing condition. The effect of parallel injection on hydrogen concentration profile was clarified. It seemed that there was the stoichiometric condition at the outer edge of shear layer. It was confirmed that the diffusion of Hydrogen, including turbulent mixing, had an effect of flow configuration.
