高效风能离心泵水力性能优化匹配研究的中期报告
【摘要】
本文以高效风能离心泵为研究对象，探究其水力性能优化匹配的研究。采用ANSYSFluent软件建立了高效风能离心泵的三维流场数值模型，并通过计算流场及其水力性能参数，确定离心泵的基本水力性能。在此基础上，应用正交试验法选取合适的试验参数，结合响应面分析法研究了泵水力性能的优化匹配问题。研究结果表明，针对不同的流量和扬程工况，可以通过合理调整泵的叶轮直径、叶片数目、进口导叶角度等试验变量，实现泵水力性能的优化。此外，通过比较不同工况下泵的性能曲线，发现离心泵的运行效率与叶片直径及进口导叶角度的关系较为密切，该研究为离心泵的设计以及风能利用系统的优化提供了一定的理论参考和实验依据。
