摘要
以某水电站轴流转桨式水轮机为研究对象,对机组引水管道、蜗壳、固定导叶、活动导叶、水轮机转轮以及尾水管等过流部件进行实际尺寸三维建模,对水轮机进行全流道三维数值模拟,根据模拟计算结果对转轮叶片进行改型设计,并利用CFD以及转轮效率计算,验证了新叶片性能的提升。
In this paper,the authors,taking the axial flow propeller turbine of a water power station as the research object,established three-dimensional model for the flow passages,volutes,fixed guide vanes,movable guide vanes,turbine runners and draft tube,etc.,the parts on which water flows with actual dimensions,carried out entire flow passage three-dimensional numerical simulation for the turbine.Based on the calculation result,the authors modified the the rotor blade,and verified the improvement in performance of the new blade,by means of CFD and calculation of rotor blade efficiency.
