Abstract
In view of strong non-linear relationship between shape parameters and overall efficiency of the blade of micro-head pump-turbine,this paper presents an optimization method for blade of micro-head pump-turbine based on response sur-face model and NSGA-Ⅱalgorithm. It firstly adopts the orthogonal design method for scheme design on blade shape parame-ters which is taken as training sample for building the response surface model as well,and then uses optimal Latin hypercube design method to design a scheme for geometrical shape parameters of reel blade which is taken as testing sample. Next,it u-ses Fluent software to perform numerical simulation on designed schemes and calculates simulation values of overall efficien-cies under hydraulic turbine condition and water pump condition that are taken as optimized objects so as to establish a re-sponse surface model for relationship between overall efficiency and blade shape parameters. Then it applies NSGA-Ⅱ algo-rithm for optimizing the response surface model and obtain optimal blade shape parameters. External characteristic test for the optimal scheme indicates numerical simulation values are basically consistent with results of physical experiment,which verifies reliability of numerical simulation values and feasibility of the proposed optimized design method for blade of micro-head pump-turbine.关键词
