基于环量分布的离心叶轮S2流面设计与优化
Design and Optimization for Centrifugal Impeller S2 Streamsheet Based on Circulation Profile
摘要
Abstract
The three typical impeller designs with quasi-three-dimensional flow method was presented. Streamwise circulations were specified along meridional hub and shroud boundaries. Laplace equation was solved to distribute the circulation on the meridional surface. Impellers were designed for afore-loaded, uniform-loaded and aft-loaded ones. Their flow performances were compared though CFD simulations. Results show that uniform-loaded impeller has better performance than the other two ones. Blade circulation profile can be controlled easily by Bezier lines and Laplace equation.关键词
