Quasi-2D Turbomolecular Pump

Application ID: 67021


The Monte Carlo simulation of flow in a turbomolecular pump can be greatly simplified if the mean radius of the blades is much greater than the spacing between them. Under these conditions, the rotating blades of the pump can be approximated as an infinite row of blades having only translational velocity.

This benchmark model shows the effect of blade velocity, angle, and spacing on the transmission probability of molecules across a single-stage turbomolecular pump in the free molecular flow regime. The results agree well with earlier publications using the same simplifying assumptions.
