直接模拟蒙特卡罗法在稀薄气体模拟中获得了成功的应用。然而，在处理连续介质传热和流动问题时，模拟的速度极大地制约了该方法的应用。尤其对于大系统的连续流动，该方法的收敛速度几乎无法实现。鉴于此，本文通过引入超粒子，对直接模拟蒙特卡罗方法进行改进，并将其应用于连续介质传热和流动模拟之中。
Direct simulation Monte Carlo method has been successfully applied into simulation of rare gas. However, while treating with some question such as heat-transfer and flow of continuous fluid, speed of simulation extremely restricts its application. Especially for continuous fluid of large system, this method isn't almost able to achieve in its convergence speed. According to the points mentioned above, this paper improved direct simulation Monte Carlo method through a model of super particle to realize simulation for heat-transfer and flow of continuous fluid.
