A CFD investigation on hydrodynamics characteristics of gas liquid ejector has been carried out to study the influence of gas liquid flow rates ratio on the performance and on the mass transfer characteristic of ejector. In this study, the ejector design was modeled using finite volume CFD techniques to resolve the flow dynamics in the ejectors. The CFD results were validated with available experimental data. Flow field analyses and predictions of ejector performance were also carried out. During validation, although there is a discrepancy between CFD and experimental results, however it has a good agreement in the trend of phenomena respect to experimental results. From the present analysis, it can be concluded that the efficiency of the ejector increases with respect to gas liquid flow rates ratio. It also can be seen that the volumetric mass transfer coefficient is higher when the gas flow rate increased.
