摘要

本文对四分之一螺距扭流式萨伏纽斯涡轮进行了计算流体力学分析。利用Flow science开发的CFD软件包Flow 3D对该涡轮进行了仿真。采用结构矩形网格的雷诺平均Navier-Stokes方程(RANSE)求解器进行了数值模拟。所提出的转子由无中心轴和重叠比为0.35与两个端板。涡轮在参考平面上绕z轴旋转，具有6个自由度。对汽轮机进行了恒流转速和一组变转矩的模拟。仿真结果表明，该水轮机效率可达7%以上，可作为海流水轮机使用。

Performance of a quarter-pitch twisted Savonius turbine

The paper presents Computational Fluid Dynamics analysis of a quarter pitch twisted Savonius turbine. The turbine has been simulated using a CFD software package Flow 3D developed by Flow science. The simulation has been done using Reynold's Averaged Navier-Stokes Equations (RANSE) solver with structured rectangular mesh. The proposed rotor consists of no central shaft and has an overlap ratio of 0.35 with two end plates. Turbine rotates around z axis in the reference plane with six degree of freedom. The turbine is simulated for a constant current speed and a set of variable torques. The simulation result shows that the turbine can achieve more than 7% efficiency and can be used as a marine current turbine.
