| 摘 要： | 在离心泵前加置诱导轮是保证离心泵获取优越汽蚀性能的关键途径。针对某型号液体火箭发动机诱导轮,采用CFD技术研究了轮毂型线形状对诱导轮汽蚀性能和扬程的影响。结果表明,在具有相同入口流动状态条件下,改变诱导轮轮毂型线形状可使诱导轮产生不同扬程。

| Abstract: | The inducer mounted in front of the centrifugal pump is a key way to ensure the centrifugal pump to achieve the excellent cavitation performance.In allusion to the inducer of a certain liquid rocket engine,CFD technique was adopted for researching the influence of hub shape on the cavitation performance and pumping head of inducer.The results show that,under the condition of the same inlet flow,changing the inducer-hub shape can make the inducer to generate the different pumping head. |
