基于FLUENT滑移网格的浮选离心叶片泵内流场的CFD分析

摘要

The performance of centrifugal pump have an important influence on the stability and efficient of flotation process in equipment of flotation. In order to catch the variation of flow field inside of centrifugal pump, the sliding mesh technology in fluent software is used to numerically simulate the flow in centrifugal pump, and then * analyzed the flow variation inside of centrifugal pump with vane rotating, and obtain the total pressure graphs, velocity - vector graphs and turbulent kinetic energy graphs. Thus lays the foundation for the design and the structure optimization of centrifugal pump.%在浮选设备中离心泵的性能对浮选过程的平稳性和效率有着重要影响.为了准确掌握离心泵内部流场的变化情况,运用FLUENT软件中的滑移网格技术对叶片武离心泵进行流场动态数值模拟.分析得出叶片旋转情况下内部流场不同时间点的总压力图、速度矢量图和湍动能图,为离心泵的设计和优化奠定基础.
