| 摘 要： | 基于三维反问题设计方法,结合CFD数值模拟,以混流泵叶片载荷分布参数为设计变量,以水力效率为优化目标,采用正交试验方法和响应面函数法建立设计变量与目标函数的关系,对混流泵进一步优化。分析了不同设计变量对目标函数的影响,发现叶轮轮盘进口处载荷对泵的水力效率影响最明显。通过数值模拟对比基准叶轮与优化叶轮性能,优化后的混流泵模型最优工况下的水力效率提高3.2%,且水泵扬程基本保持不变,优化体系具有良好的工程应用价值。

| Abstract: | A reliable and convenient optimism method was introduced. Based on a mixed-flow pump designed by 3-dimensional inverse design method and combined with CFD, an optimization design was conducted with the blade-loading as the design variable and the hydraulic efficiency as the optimization objective. With CFD simulation results, the relationship between the hydraulic efficiency and the blade-loading was established by orthogonal test and response surface method. The optimization results show that the blade loading on hub near leading edge has the most significant influence on the hydraulic efficiency. Compared with the pump model with the reference impeller, the hydraulic efficiency of the pump model with optimized impeller increases by 3.2% while the head keeps constant. |
