基于不同环量分布的轴流泵叶轮优化设计
Optimization design of axial flow pump impellers based on different circulation distributions
摘要
Abstract
To improve the hydraulic performance of an axial flow pump station,optimization was carried out on an axial flow pump model with a design specific speed of 900 based on a three-dimen-sional inverse(3D)design method.The impeller outlet circulation distribution was first divided into three forms:constant,linear,and nonlinear.Through orthogonal experimental design,32 sets of design schemes were determined respectively within the sample space.Computational fluid dynamics(CFD)technology was employed to perform numerical simulations on the original scheme and three circulation distribution schemes.By controlling eight impeller outlet circulation distribution parameters,parametric design of the impeller was achieved under constant,linear,and nonlinear circulation distri-bution conditions,and the pump section performance before and after optimization was compared and analyzed.The results show that the variation trend of the impeller outlet circulation under different dis-tribution forms remains basically consistent.Among them,the constant circulation distribution demon-strates the most significant optimization effect,with more stable internal flow and more uniform velocity distribution.Under the design operating conditions(flow rate:360 L／s,head:5.4 m),the efficiency reaches 79.24%,indicating a notable improvement through optimization.关键词
