摘要(Abstract):

本文介绍一种计算喷射器的新方法。该方法的特点是,处在喷射过程中,所有能量损失(包括喷嘴、混合室和扩压段)是随着流动参数和几何参数的变化而变动。文中对喷射器流动特性进行了计算,所得到的计算值是与的测量值相当吻合。因此,该计算方法可作为喷射器设计的一个改进计算方法。
A new method of calculating compressible flow ejectors has been developed, This method is characterized by all energy losses (included nozzle, mixing chamber and diffuser) to change with flow parameters and geometric parameters during the pumping processes. The flow characteristics of the compressible flow ejectors was calculated in this paper. The comparison between these calculated values and measured values by the E. is shown a good agreement. Therefore, the calculation method is an advanced method for designing compressible flow ejectors.
