Numerical Investigation of Aerodynamic Performances for NREL 5-MW Offshore Wind Turbine

As one of the preferred types renewable energy, wind energy is rapidly growing. The purpose this study to provide a comprehensive and in-depth numerical analysis on National Renewable Energy Lab (NREL) 5-MW offshore turbine help understand turbine’s aerodynamic features. In research, preprocessing was conducted by using SolidWorks modeling, realizable k-ε viscous model from ANSYS/FLUENT used as solver in CFD simulation. Eight test cases were developed, fixed inlet velocity 9 m/s set baseline case. After initial mesh independent validation, detailed carried out. results near wake flow features, torque thrust, pressure coefficient distribution, limiting streamline along blades, power function tip speed ratio evaluated. Whenever possible, simulation compared with data literature (numerical or experimental), good agreement observed. are expected valuable input design thus improve effectiveness harnessing energy. Research way further understanding influence different inflow conditions characteristics.
