Efficiency improvement of Roots vacuum pump working process Computational fluid dynamics methods modeling

In this paper influence of rotor profile type of Roots vacuum pumps on backward leakage through channels of rotor mechanism and pumping speed is considered. Elliptical, involute, and circular profiles are widely used. Backward leakage through channels of rotor mechanism with different rotor profiles...
