Abstract�� To study the interior flow of the resonance tube, the model of the nozzle-cylindrical resonance tube system was established, and the gas dynamic resonance heating effect was simulated. The explicit second-order NND scheme was used to solve the 2-D axisymmetric Reynolds averaged N-S equations. The heat transfer effects of the resonance tube were considered by heat transfer equations. The pressure and temperature oscillation curves at the resonance tube end were obtained and the computational data were in good agreement with the experimental data. The results show that gas dynamic resonance heating is performed in about twenty milliseconds, and the heat transfer effects of the resonance tube affect the temperature of gas dynamic resonance heating highly and should be considered in computation and application.
