| 摘 要： | 为了提髙诱导轮离心泵的空化性能和运行稳定性，阐明诱导轮对离心泵空化性能的影响规律，以某型船用凝水泵为研究对象，采用数值模拟手段预测前置诱导轮的空化性能，同时预测了多工况下叶轮的空化性能。数值模拟结果表明：在小流量工况和额定工况下，空化性能曲线基本一致；在大流量工况下，空化特性曲线波动相对比较严重，空化性能较差。

Numerical study on influences of inducer on cavitation performance of centrifugal pump |
| |
| Abstract: | In order to study the effects of the inducer on the cavitation performance and to improve the cavitation performance and operation stability of the centrifugal pump,the simulation method is launched.The numerical results show that the cavitation performance curves are basically the same under the condition of small flow conditions. Under the condition of large flow, the cavitation characteristic curve fluctuation is relatively serious and the cavitation performance is poor. |
