Abstract

This paper describes a numerical study of liquid jet gas ejector in a vacuum pump. An experimental model of liquid-gas ejector was used in this simulation study. The realisable 𝑘 – 𝜀 turbulence model was utilized in RANS simulation. Investigations were realised at various liquid velocities from 2 – 10 m/s and remained constant gas velocity at 0.02 m/s. The CFD validated pressure is in good agreement with the available experimental data. The composition of gas and liquid is to be sensitive against the mixing process of liquid-gas in the throat section which cause the specific distribution of both pressure and velocity along the channel.
