Numerical Simulation and Shape Optimization of Supersonic Ejectors for Refrigeration Applications, M.Sc. Thesis Sharif University of Technology ; Hakkaki-Fard, Ali (Supervisor)
Abstract
Due to an increasing need for refrigeration systems and consequently increasing in electricity usage and greenhouse gases production, using ejector refrigeration systems would be a suitable substitution for conventional cooling systems. Main drawback of ejector refrigeration systems is their low coefficient of performance. The key component to improve the cycle performance is the ejector. Prerequisite of improving ejector performance is an accurate CFD simulation for predicting entrainment ratio. In this study, a two dimensional, axisymmetric, steady state, compressible flow CFD simulation of a supersonic ejector is presented. CFD results are validated with experimental data. Furthermore,...
