Ejectors are widely used in many applications such as water desalination, steam turbine, refrigeration systems, and chemical plants. This project work carries the numerical simulation of the working of a steam ejector in order improve the performance. Computational Fluid Dynamics (CFD) was employed for the numerical simulation. In this paper the effect of operating conditions on the performance of the steam ejector operating in conjunction with an ejector refrigeration cycle was considered. Also the effect of one of the geometry parameter was also examined. The model was created and meshed using GAMBIT 2.4.6. The meshed geometry was then exported to FLUENT 6.3.26 and the analysis was carried out using FLUENT. The analysis was carried out for different operating conditions and different geometries. The results obtained from the analysis shows that the CFD technique can be used for carrying out the performance evaluation of a steam ejector.
