摘要

本研究旨在利用计算流体力学方法了解转子半径比对混合垂直轴风力机Savonius-Darrieus NREL S809模型性能的影响。双叶片Savonius用作内部转子，三叶片Darrieus NREL S809用作外部转子。通过力矩系数和功率系数的取值来分析汽轮机模型的性能。结果表明:转子半径比的增大导致初始弯矩系数增大，最大功率系数减小;在初始TSR时，转子半径比0.5模型的弯矩系数值最好，而最大功率系数值最低。

The Effect of Rotor Radius Ratio on The Performance of Hybrid Vertical Axis Wind Turbine Savonius-Darrieus NREL S809

This research aims to know the effect of the Rotor Radius Ratio on the performance of the hybrid Vertical Axis Wind Turbine Savonius-Darrieus NREL S809 model using the Computational Fluid Dynamics method. Two-bladed Savonius is used as an internal rotor, and three-bladed Darrieus NREL S809 as an external rotor. Turbine model performance is analyzed through the value of the Moment Coefficient and Power Coefficient. The result shows that the increase in the Rotor Radius Ratio value causes an increase in the initial Moment Coefficient but a decrease in the maximum Power Coefficient value. At the initial TSR, the Rotor Radius Ratio 0.5 model has the best Moment Coefficient value among all variations but has the lowest maximum Power Coefficient value.
