| 摘要: |
| 采用DSMC（Direct Simulation Monte-Carlo）方法模拟二维凹槽过渡流动，给出了在不同Knudsen数、不同展弦比、不同壁温条件下凹槽流的速度和温度分布，并对DSMC方法在模拟全速度域流场时存在的局限性进行了讨论。 |

| Abstract: |
| The transitional fluid flow in a two-dimension groove is simulated by DSMC method. The velocity vector and isotherm are shown at different Knudsen numbers、different span-chord ratios and different temperature wall. The limitation of the DSMC method in simulating the all-velocity flow field is also discussed. |
| Keywords: DSMC method groove transitional flow |
