Abstract

Two different types of ejectors used for pumping gas, liquid and two-phase flows, as well as for evacuation of enclosed spaces have been analyzed. The results of CFD simulation of Dubinsky's Vortex ejector operation process are presented. The results of numerical simulation and experiment for different modes of ejector operation for passive flow and total back pressure are compared.
