Abstract
This study involves aerodynamic analysis of drag-driven wind turbines performed using the open-source computational fluid dynamics software OpenFOAM®. Numerical solutions were performed for two-space dimensions assuming that blade shapes and orientation do not change in the vertical direction. Since the solution domain contained rotating and non-rotating sections, the MRFSimpleFoam solver, which contains multiple rotating reference frames, was used for computations. Turbines with circular-arc-shaped blades were analyzed and compared for different tip speed ratios and blade number. Numerical solutions were performed for two-space dimensions assuming that blade shapes and orientation do not change in the vertical direction. Computed power coefficients were very low showing an oscillatory behavior for all cases.
