摘要
以一种单级喷嘴挡板式电-气压力伺服阀为研究对象,运用Fluent软件对其喷嘴挡板级内部流场进行数值计算,分析了不同喷嘴孔径大小对电-气压力伺服阀控制腔压力特性的影响,并结合试验对数值计算结果进行了验证,试验验证与数值计算结果较为一致,为喷嘴挡板式电-气压力伺服阀的工程设计提供了参考。
Researching on a nozzle flapper electro-pneumatic pressure servo-valve, the numerical simulation of flow field inside the nozzle flapper is accomplished with FLUENT software, mainly analyze the influence of nozzle diameter on back-pressure. Experimental study is also provided and numerical simulation coincides with the experimental result, which can give references for the design of the nozzle flapper electro-pneumatic pressure servo-valve.
