Development of applied software for analysis of gas flows in vacuum devices

摘要

The paper presents some results of computing gas mixture flows in Knudsen and Holweck pumps. Transient flow development processes and attainment of the steady state are considered. The calculations were performed using a problem solving environment developed by the authors. A conservative projection method of solving the Boltzmann kinetic equation upon which the problem solving environment is based is described. The paper is aimed to demonstrate the capabilities of the software at the actual stage of its development.
