On the basis of thermodynaeic principle and the introduction of gas flow dynamic function, a computational model of steam ejector is set up and the computational methods of performance parameters such as entrainment ratio and compressed vapor pressure of steam ejector are presented. The paper calculates and analyzes the effects of working steam pressure, motive steam pressure and compression ratio on the best entrainment ratio as well as the relation feature between the entrainment ratio and compression pressure and ratio. The results offer a theoretical foundation and an effective calculation method for the design of thermal parameters for steam ejectors.
