CFD Analysis of Ejector Use in Refrigeration System
Author : Scholar Nawed Aqbal Khan, Professor Dr. Ajay Singh, Nitin Barodia Journa Name: International Journal of Science, Engineering and Technology Country : India Volume: 12 issue: 3 Year: 2024 Views : 367The refrigeration system plays an important role in various applications from households to industries. An ejector refrigeration system is one of the thermal driven refrigeration systems. In this study, the performance and optimization of ejectors predicted by the RANS-based CFD model were examined. The effects of primary nozzle throat diameter and primary nozzle discharge diameter were investigated and analyzed to better understand the phenomena inside the ejector. Findings indicate that a critical condenser pressure of 236585 Pa was observed at optimum level of primary nozzle throat diameter of 1.5 and primary nozzle discharge diameter of 9.6. The application of RSM method improves the effectiveness of ejector. Best result is achieved from applying of RSM method.
