| Abstract: | Water-ring vacuum pump was widely used in vacuum pumping industries for its unique characteristics.To understand the gas-liquid two-phase flow characteristics of the water-ring vacuum pump,the CFD software based on the VOF two-phase model was utilized.Sliding mesh and two-order upwind discretization method were adopted to solve the RANS equations.Gas-liquid two-phase flow field in the typical water-ring vacuum pump was analyzed,and the result confirms the feasibility of the numerical method used in this paper.The paper’s work can be able to supply theoretical study to increase the efficiency of the water-ring vacuum pump. |
