摘要
利用流场直接模拟的ＭｏｎｔｅＣａｒｌｏ（ＤＳＭＣ）方法数值模拟了Ｒａｙｌｅｉｇｈ问题的流场，获得了相应的结果，结果与解析解及经验解吻合较好．ＤＳＭＣ方法避免了求解复杂的控制方程，在流动比较复杂的情形下，有很大的优越性。
Adopted DSMC method numerically simulating the flowfied of Rayleigh problem,gained correspond results,which conformed well with the analytical results and experienced results.DSMC method avoids solving complex controlling equations,has much advantage in condition of complex flow.Its a good method in researching rarefide.
