| 摘 要： | 利用CFD数值模拟手段，对射流元件内部流场进行模拟，并对数据进行分析研究,得出结论为：在空载作用下，元件在一侧出流。赋予不同的主喷嘴流量，元件的属性各参量变化不大，可见，元件结构既定，元件射流附壁属性基本确定。该模拟仿真分析丰富了射流元件内部流动的理论研究，完善了参数设计,这对射流式冲击器的设计理念和理论研究有很好的指导意义。

| Abstract: | In this paper, flow field inside jet element was simulated with CFD numerical simulation, and the results were analyzed. While with no-load, jet flow attached to and out flowed from one side of the jet element. With different flow to main nozzle, difference of parameters and characteristic of the jet stream is not obvious, so the conclusion is that wall-attached property of jet element is stable with existing structure. This simulation enriched theory of inside flow in jet element and perfected parameter design. |
