引射器由喷嘴、混合室、扩压器三部分组成(图1)。工作流体经过拉瓦尔喷嘴绝热膨胀,压力势能转换为动能,在喷嘴出口之后形成低压超音速湍流射流。射流与环境被引射流
Ejector from the nozzle, mixing chamber, diffuser three parts (Figure 1). The working fluid is adiabatically expanded through the Laval nozzle, and the pressure potential energy is converted into kinetic energy to form a low-pressure supersonic turbulent jet after the nozzle exit. Jet and environment are jetted
