摘要
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 illto simulation of rare gas. However, while treating with some question such as heat-transfer andflow 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 conver-gence 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 fiuid.
