ON ENGINEERING APPLICATION OF KNUDSEN COMPRESSOR TO VACUUM PUMPING SYSTEM

摘要

We consider an engineering application of the Knudsen pump. The Knudsen pump is a new vacuum pumping system that utilizes a thermal transpiration flow that is peculiar to a rarefied gas. There is no moving part in this pumping system and the mechanism is so simple that many possible applications are predicted. In this paper we investigate the basic features of the Knudsen pump numerically, and suggest the possible application to the position control of the space artificial satellites.
