基于CFX的中比转速离心泵的性能特性预测
CFX-Based Performance and Characteristics Forecast of Medium Specific Speed Centrifugal Pump
摘要
Abstract
Taking a medium specific speed centrifugal pump with given parameters and twisted blades as research objective, the hydraulic design are studied. The three-dimensional model of pump is established by UG NX6.0, and the grid is divided by ICEM CFD after importing the 3D fluid zones model in parosolid form which is exported by the UG software to CFX. The internal flow field is simulated by ANSYS CFX12.1. The performance of centrifugal pump is forecasted and the heads and shaft powers at design conditions and other typical off-design conditions which reflect the extra characteristics of pump are obtained. The flow-head and flow-efficiency curves conform to the general laws of centrifugal pump. The study can provide references to the design and optimization of centrifugal pump.关键词
