| 摘 要： | 基于直接模拟Monte Carlo(DSMC)方法,从描述粒子微观运动层次出发,构造高空稀薄环境下气体一颗粒两相双向耦合作用的热力学模型,发展适用于稀薄流过渡区多相复杂流动的DSMC算法.通过算例验证,结果表明,此模型能够较好地反映相间动量和能量传输机制.

| Abstract: | Based on the DSMC method,a two-way coupled mechanical and thermal model for high-altitude two-phase rarefied flow is presented with considering of particles' micro flow properties.An approach of DSMC is developed for multiphase flow in the transitional regime of rarefied gas.Simulations are performed for the verified case and the results show that the model agrees closely with the momentum and energy transfer mechanism. |
