Supersonic ejector-diffuser system makes use of high pressure primary stream to propel the secondary stream through pure shear action for the purposes of transport or compression of fluid. The optimization of the ejector-diffuser system and its optimal operation condition are hardly known due to the complicated turbulent mixing, compressibility effects and even flow unsteadiness which are generated inside the ejector-diffuser system. In the present study, a Chevron nozzle was applied to activate the shear actions between the primary and secondary streams, by means of longitudinal vortices generated from the Chevron. Exactly same geometrical model was created to validate the results of experimental data. The operation characteristics of the ejector system were compared between Chevron nozzle and conventional convergent nozzle for the primary stream. A CFD method has been applied to simulate the ejector-diffuser flow field of the supersonic flows and shock waves. The ejector-diffuser system performance is discussed in terms of the entrainment ratio, ejector efficiency, pressure recovery as well as total pressure loss.
