This paper presents the numerical analysis performed on ejectors to optimize operating conditions like evaporator temperature, condenser temperature and generator temperature. R245fa was the working fluid used. Parametric analysis was performed to study the effect of mixing chamber geometry on ejector performance which has direct impact on coefficient of performance of ejector refrigeration cycles. Results show that operating conditions and geometric parameters have a value or range of values for which entrainment ratio of ejector is maximum.
Keywords:- Ejector, entrainment ratio, CFD, ANSYS, optimization, operating conditions.
