摘要
考虑了正激波穿过气体/液滴两相混合物引起的液滴碰撞聚合现象。分析了波后气液相的状态变化及惯性差异引起的波后相间速度、大小2类液滴间速度的差异,用随机过程理论描述了液滴的碰撞概率,对其数目变化建立了生灭过程模型,由模型方程的解得出数目分布和均值,并由此估计液滴碰撞聚合的效果。
The phenomena of droplet collision and coalescence were considered,which taking place in the gas-droplet tow-phase flow caused by a normal shock wave traveling in the gas-droplet mixture. The gas and liquid states,and the velocity differences between two phases and two kinds of liquid droplets were analyzed.The stochastic process theory was introduced to describe the droplet collision probability,and a birth-death process model on their number change was established.The distribution and mean of droplet number were obtained to estimate the effects of droplet collision and coalescence by solving the relevant model equation.
