摘　　要：运用建立的初始几何模型模拟了PEMFC发动机系统氢气喷射器各工况的工作流体压力,每个工况保持引射流体压力和混合流体压力不变,分析工作流体压力对喷射器性能的影响规律。选取部分工况模拟了喷射系数随引射流体压力和混合流体压力的变化规律。The working fluid pressure of each working condition of hydrogen ejector flow field for PEMFC engine system was simulated by the initial geometric model. Each condition kept lead jet-fluid and mixed-fluid pressure unchanged. The influence law of the working fluid pressure on the ejector performance was analyzed, The variation law of the injec- tion coefficient with the jet-fluid and mixed fluid pressure was simulated in some conditions,
