| 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 |
