| Summary: | 碩士 === 大葉大學 === 機械工程研究所碩士班 === 94 === Present work conducts numerical calculations with CFD (computational fluid dynamics) software to determine the aerodynamic characteristics of the NREL PhaseII experimental wind turbine. In this study, the governing equations, consisting of three-dimensional time-dependent conservation of mass, momentum,and energy, are solved using the SIMPLEC numerical scheme.To treat the turbulence effect, the k-ε two-equation turbulent model is adopted as the turbulence closure. Using an untwist, constant chord length, non-symmetrical
airfoil as the design baseline of the NREL PhaseII experimental wind turbine, important aerodynamic properties, including Cp (Pressure Coefficient)、Moment、power, are determined under board ranges of wind speed and pitch angle. Predictions can be then readily served as the input loading conditions for further the aeroelastics analysis.
