摘要
直接模拟蒙特卡罗方法(DSMC)通过计算机跟踪仿真分子的运动,求解稀薄气体流动规律.选用硬球模型模拟仿真分子间的碰撞,编写DSMC的计算程序,模拟处于滑流和过渡流动领域的二维微槽道内气体流动.结果表明,气体流动在边界附近出现速度滑移和温度跳跃.计算结果和理论值相吻合.
Direct simulation Monte Carlo method is a technique with which a rarefied gas flow is simulated by using computing model of thousands of testing molecules. DSMC method is written to solve the couette flow between two parallel plates. Models for intermolecular collisions are assumed to be hardsphere models. The results show that there exist velocity slip and temperature dump near the boundary.
