对单独供应可燃混合物成分、氢气和空气的环形旋转爆震室（RDC）的运行进行了三维数值模拟，并将计算结果与现有实验数据进行了比较。该模型基于瞬态雷诺平均纳维-斯托克斯方程系统，辅以多组分反应气体混合物的湍流模型以及连续性和能量方程。该系统采用基于有限体积法和粒子法的耦合算法进行求解。首次进行计算时考虑了可燃混合物组分之间以及反应和爆炸产物的有限湍流和分子混合速率的影响。计算结果与俄罗斯科学院西伯利亚分院拉夫连季耶夫流体动力学研究所获得的实验数据相媲美。
A three-dimensional numerical simulation of the operation of an annular rotating-detonation chamber (RDC) with separate supply of combustible mixture components, hydrogen and air, is performed, and the calculation results are compared to available experimental data. The model is based on a system of time-dependent Reynolds-averaged Navier-Stokes equations complemented with a turbulence model and continuity and energy equations for a multicomponent reacting gas mixture. The system is solved using a coupled algorithm based on the finite volume method and particle method. Calculations are for the first time performed with allowance for effects of finite rates of turbulent and molecular mixing of the combustible mixture components with each other and with reaction and detonation products. The calculation results compare favorably with the experimental data obtained at the Lavrentyev Institute of Hydrodynamics of the Siberian Branch of the Russian Academy of Sciences.
