Comparison of traditional and CRMC ejector performance used in a steam ejector refrigeration
Energy Procedia, 2017 Abstract In this paper, performance of a steam ejector designed based on the constant rate of momentum change (CRMC) and traditional ejector were tested in an attempt to compare its performance. Three different ejectors were designed and constructed; traditional ejector with throat diameter of 19 mm, traditional ejector with throat diameter of 13.4 ...
