摘要
Abstract
Based on the existing mathematical model of mass entrainment ratio, a hybrid model for single phase R744 ejector system was developed. Firstly, based on the fluid dynamics and heat transfer theory, a theoretical model of mass entrainment ratio was established, and then it was simplified by considering the fluid status at the ejector inlet and outlet. The obtained new mathematical model contains five unknown parameters, and the fitting method for the parameters is also given. The comparisons of the calculation and experimental results indicate that the new model has a higher accuracy.关键词
