Simulation of flow field in steam ejector and analysis of shock wave characteristics
Shanghai Aircraft Design and Research Institute, Commercial Aircraft Corporation of China Ltd, 5188 Jinke Road, Shanghai, China
Fluent software is used to simulate the two-dimensional flow field in the steam ejector. The generation, development and end of shock in the flow field are analyzed. The influence of the shock wave characteristics on the ejector performance is discussed. The results show that the working back pressure in the steam ejector and the throat diameter of the nozzle all affect the position and intensity of the shock wave. When the shock wave ends prematurely or belatedly , it all affect the performance of the injector.
