Wind energy is
recognized as a sustainable source of energy that is both reliable and capable
of dramatically reducing pollution to the environment and dependency on
non-renewable fuels, leading to research on wind turbines. Nowadays, the demand
for electricity increases. Considering that the greater the distance from
shore, the greater the wind, more electricity will be generated along the
coast. It is necessary and beneficial to study large scale offshore wind
turbines. The National Renewable Energy Lab (NREL) 5-MW offshore wind turbine
is simulated using a three-dimensional computational fluid dynamics (CFD) model
in this article. A realizable k-ε viscous model is used to simulate turbulence
flow. The work is validated by comparing the torque with published simulated
data, and satisfied consistency is observed. Further simulation and
comprehensive analysis demonstrate the flow features and aerodynamic
performances of 5-MW offshore wind turbine under various wind and rotor speeds.
The velocity profiles, total pressure distribution, pressure coefficient, rotor
thrust, torque and aerodynamic properties are obtained in detail.
