The numerical and approach for improving the performance of the control device for molecular gas flow have been done. By using the direct simulation of Monte Carlo method (abbreviated into DSMC method), the deposition rates on glass blade for the control device and rarefied gas flows around the blades are simulated and evaluated. It is revealed that the rate by the DSMC method can estimate accurately the experimental data of deposition rate of carbon molecules on blades in a vacuum deposition machine. By the controlling the axial bearing with a permanent magnet, the rotational rate of the control device for molecular flow can be increased by 2.5 times to 5.5 times.
