直接模拟蒙特卡罗(DSMC)模型自20世纪60年代由Bird首次提出以来,已被成功地应用于描述各种环境中的气体流动。在这项工作中,我们提出了一种新的方法来模拟气相颗粒之间的碰撞-操作方式类似于DSMC模型,但有一个关键的区别。粒子在由所有先前传播的粒子产生的平均场中运动,这消除了所有粒子同时传播的要求。这大大减少了计算工作量,并适合于难以处理的应用程序,例如当感兴趣的物种只是大型气体混合物的一小部分时。
Direct simulation Monte Carlo (DSMC) models have been successfully adopted and adapted to describe gas flows in a wide range of environments since the method was first introduced by Bird in the 1960s. We propose a new approach to modelling collisions between gas-phase particles in this work – operating in a similar way to the DSMC model, but with one key difference. Particles move in a mean field, generated by all previously propagated particles, which removes the requirement that all particles be propagated simultaneously. This yields a significant reduction in computation effort and lends itself to applications for which DSMC becomes intractable, such as when a species of interest is only a minor component of a large gas mixture.
