| Abstract: | Effects of thermodynamic and geometry parameters on the properties of flow field with various boundary conditions and structural dimension were studied by numerical computation. The factors affecting the appearance of shock wave which causes a great lose of the ejector performance were analyzed. A mathematical model and computation method for the supersonic jet flow in the ejector nozzle were established. |
