Study on force characteristics of guide vane and blade of axial flow hydro-turbine with movable blade

为了正确确定轴流转桨式水轮机的接力器容量,必须掌握导叶和桨叶在各种工况下的力特性资料。通过CFD计算对某轴流转桨式水轮机进行数值分析,得到了导叶和桨叶水力学特性。通过与模型试验结果和经验公式的对比发现,CFD计算结果是可信的,可以为轴流转桨式水轮机的真机设计提供参考。

In order to correctly determine the capacity of servomotor of axial flow hydro-turbine with movable blade, the force characteristics of guide vane and blade under all conditions are required to master. Through the numerical analysis of hydro-generator by CFD calculation, the force characteristics are worked out. By comparing the test result and empirical formula, it is found that the result of CFD calculation is reliable and is able to provide reference for design of real xial flow hydro-turbine with movable blade.
