| 内容記述 | An experimental investigation was carried out on the interaction of inert and chemically reactive gaseous jets with hot supersonic airstream in the Mach 1.81 supersonic combustion wind tunnel. Highly underexpanded nitrogen and hydrogen were injected from a converging slot nozzle oriented perpendicular to the airstream. In the experiments, temperature and oxygen concentration of the vitiated airstream, and injection pressure were varied, including conditions at which chemical reaction occurred. The wall static pressure distributions, temperature profiles and pitot pressure profiles were measured on the jet interaction flowfield with chemical reaction. At the same time, schlieren photographs were taken to determine the effect of the chemical reaction on the jet interaction flowfield. The results indicated the important role of the chemical reaction in the upstream separated region caused by the jet. Chemical reaction in the upstream separated region increased the separation distance significantly. Downstream of the jet, after a small induction zone, a turbulent flame was formed in the mixing region between the supersonic airstream and the injected hydrogen. However, the effect of the downstream turbulent flame on the jet interaction flowfield is found to be small in the range of present experimental conditions. | |||||||||
