    摘要:

    基于三維反問題設計方法,，結合CFD數(shù)值模擬,，以混流泵葉片載荷分布參數(shù)為設計變量，以水力效率為優(yōu)化目標,，采用正交試驗方法和響應面函數(shù)法建立設計變量與目標函數(shù)的關系，對混流泵進一步優(yōu)化,。分析了不同設計變量對目標函數(shù)的影響,，發(fā)現(xiàn)葉輪輪盤進口處載荷對泵的水力效率影響最明顯。通過數(shù)值模擬對比基準葉輪與優(yōu)化葉輪性能,，優(yōu)化后的混流泵模型最優(yōu)工況下的水力效率提高32%,，且水泵揚程基本保持不變，優(yōu)化體系具有良好的工程應用價值,。

    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.
