摘要本文对水压式萨沃纽斯水轮机转子的流动和性能进行了数值模拟。采用单元内涡（VIC）法和体积惩罚（VP）法对流动进行了模拟。采用自定义方法计算作用在转子上的转矩，该方法可以准确计算VIC-VP方法模拟流动中对固体的流体力，从而分析转子的转速和输出功率。模拟的叶片周围流动与实验的可视化流动基本一致，分析的转子转速与输出功率的关系与实验测量的关系基本一致。这表明，VIC-VP方法与作者提出的流体力计算方法相结合，适用于水轮机的流动和性能模拟。
Abstract This study is concerned with the numerical simulations of the flow and performance of a rotor of a hydraulic Savonius turbine. The flow was simulated using the vortex in cell (VIC) method in combination with the volume penalization (VP) method. The torque acting on the rotor was computed using a custom method, which can accurately calculate the fluid forces on solid bodies in flows simulated by the VIC-VP method, to analyze the rotational speed and power output of the rotor. The simulated flow around the rotating blades agreed qualitatively with the experimentally visualized flow, and the analyzed relation between the rotor’s rotational speed and power output agreed with the experimentally measured relation. These demonstrate that the VIC-VP method in combined with the authors’ method for calculating fluid forces is applicable for the simulations of flow and performance of hydraulic Savonius turbines.
