The investigation of gasdynamic and thermal processes in the resonant interaction of a supercritical-pressure jet with a cylindrical cavity
Abstract
An analysis is presented of gasdynamic and thermal processes in a resonance tube when a supercritical-pressure jet interacts with the tube in a low-frequency pulsation regime of interaction. The effect of jet stagnation-temperature on the heating of the gas in the cavity is evaluated, and attention is given to the following characteristics: the change of averaged jet parameters as a function of distance to the nozzle section; the effect of the internal-to-external pressure ratio of the jet on the change of gas and wall temperature with time; and the change of the gas equilibrium-temperature as a function of the internal-to-external pressure ratio of the jet. The theoretical results are compared with experimental data.
