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 |
