Numerical simulation of gas-liquid venturi ejector

A three dimension dynamic Eulerian model for numerical simulation of the gas-liquid venturi ejector is established based on finite volume method and two phase RNG k - epsilon turbulence model. The gas and liquid flows are modeled using the Eulerian technique, in which turbulent kinetic energy and its dissipation rate for each phase are taken into account. Reynolds averaging is used to obtain a. set of Reynolds-averaged conservation equations for the mass and momentum, and the RNG k - epsilon turbulence model. Those aim, under a certain condition of water inlet, at obtaining a better understanding of the relationship between gas and water flow. The CFD modeling allows the simultaneous evaluation of gas, liquid and gas-liquid flow field. Thereby the Eulerian model results, in a certain extent, were in good consistence with the experimental data available in the literature. Those will helpful for design and optimization of gas-liquid venturi ejector.
