Abstract

Gradually expanding gap in the outlet of the Roots blower can effectively reduce the backflow impact and the noise of the blower. The working principle for the Roots blower with the gradually expanding gap is investigated in this paper. And the mathematical modelling for backflow is proposed. Numerical methods are given to solve the outlet gap size. The performance parameters of different dimension gap are compared. The outlet flow field in Roots blower with gradually expanding gap is simulated by means of CFD simulation. Finally, the correctness of the numerical solution is verified.
