摘要 为了研究脉冲爆轰发动机冲击波外流场的变化特点,利用CE/SE方法,推导了二维粘性湍流模型的网格数学离散模型。计算中采用标准kε两方程湍流模型,对于近壁区域采用低雷诺数模型进行处理。模拟得到了脉冲爆轰发动机外流场中压力、温度的变化规律。模拟结果表明,脉冲爆轰发动机外流场中存在相互作用的旋涡、激波和膨胀波。模拟结果对脉冲爆轰发动机外流场特性研究具有重要的参考价值。 In order to investigate the variable characteristics of the shock wave external flow field of pulse detonation engine (PDE), by use of two-dimensional viscous space-time conservation element and solution element (CE/SE) method, the mathematical and discrete grid model was derived. Standard k-ε two- equation turbulence model was used in calculation, and Low-Reynolds model was used to deal with the problem of the domain on wall. Changing rules of pressure and temperature outside PDE were acquired in the simulation. The simulation results indicated that there are several interacting vortexes, shocks and expansion waves in external flow field of pulse detonation engine. All of the simulation results provide an important reference value for research of the characteristics of flow field outside pulse detonation engine.
