Simulation of Effect of Structural Parameters on the Ejector

The effect of structure size on the flow field in the ejector was investigated by simulating structural parameters of ejector. Simulation results show that the shock occurred in the flow field of the ejector. The entrainment coefficient shows different trends as different structure parameters change. The effects of nozzle position, inlet diameter and nozzle exit ratio were studied respectively. The simulation result revealed that the structural parameters impact the performance of the gas ejector, having certain engineering application value.
