蒸汽喷射器流场模拟及性能优化分析

摘要

The numerical simulation for the internal flow field of the used for solar jet refrigeration system and the optimization analysis for the performance were carried out .Using the R134a as the refrigerating working medium ,the effect of the structure size and working parameters of the injector for its performance was analyzed .In addition,the best working range is given .%对应用于太阳能喷射式制冷系统喷射器的内部流场进行了数值模拟，对其性能进行了优化分析；选用制冷工质为R134a，通过数值模拟，研究了喷射器结构尺寸及工作参数对其性能的影响及其最佳的工作范围。
