1-D PERFORMANCE ANALYSIS OF TWO STAGE EJECTOR REFRIGERATION SYSTEM
In the present study, a 1-D analysis for the prediction of two-stage ejector performance is carried out. Constant pressure mixing is assumed in both ejectors at critical mode of operations. The results obtained from the present model are validated by Huang et al.  and found to be in good coherence. The maximum critical pressure of two-stage ejector is also calculated and found a moderate deterioration of it with increase in area-ratio. Further optimization of area-ratio is done and obtains a better performance as compare to single stage ejector on same operating conditions.
