CO2两相喷射器性能和建模的研究现状
Research Status of CO2 Two-Phase Ejector Performance and Modeling
摘要
Abstract
The application of ejector in transcritical CO2 vapor compression systems results in enhanced system performance.In the paper, the influences of system operating conditions, ejector geometric parameters and shock waves characteristics on the performance parameters of CO2 two-phase ejector were discussed, the application and development of theoretical models were expounded.It is concluded that the status of the motive fluid inlet has a greater influence on the ejector performance than the suction fluid, the nozzle throat area and the size of mixing chamber have a great influence on the performance of ejector.The visualization of shock waves characteristics needs further development. Modeling studies diversify and the CFD models still need to expand the applicability, the accuracy of flow model and shock waves characteristics, and other models with small computational costs should also expand its applicability and accuracy.关键词
