| 摘 要： | 以索科洛夫的引射器设计方法为基础,对一个高压质子交换膜燃料电池系统(PEMFC)的引射器进行结构设计以及CFD仿真分析,研究了引射器的使用特性.研究表明:随着压缩流体出口压力和引射流体压力的增加,引射器的引射系数随之增大;工作流体压力对引射器性能的影响随引射器出口所处工况的变化而变化.

| Abstract: | According to a high-pressure proton exchange membrane fuel cell system , the size of the ejec-tor and did the CFD simulation was designed on basis of the Sokolov ejector design theories , research on the ejec-tor potential performance was carried out .The results show that：①Increasing the ejector outlet pressure and e-jector fluent presser will improve the ejecting factor .②the working fluid impact on the performance of the ejector is more complex , and cannot simply be summarized as increased or decreased , but depends on the value of the outlet pressure of the ejector . |
