Abstract—The DSMC method was applied to accomplish the simulative calculation of the performance of the disk-type molecular pump for N2 and the effect of the main mechanical parameters of its channels while the parameters of the external structure were fixed. The main problems in using DSMC method such as the setting of the boundary conditions, which especially cater to the high rotative speed condition was solved. A new subassembly with optimized mechanical parameters was give out based on the calculation result.

Index Terms—Disk-type molecular pump, DSMC method, simulative, N2.
