Effect of different pitch angles on the performance parameter of the
horizontal axis wind turbine using computational fluid dynamics
Wind energy is one of the clean, sustainable types of energy that can
deal with the current worldwide non-renewable energy source emergency.
Even though it adds to 2.5% of the worldwide power request, with
depletion of petroleum derivative sources, extraction of wind energy
must reach to a more prominent degree to meet the energy emergency and
issue of contamination. Now, to improve the aerodynamic response of a
wind turbine, the blade pitch control is an effective method, usually
applied to large-scale wind turbines. The present work incorporates an
investigation of the impact of varied pitch angles on the performance
parameters of a horizontal axis wind turbine. CFD code Fluent has been
used to perform the simulations. A total of eight pitch angles are
considered in this investigation. In addition to it, a numerical
investigation of S809 airfoil has been performed and validated by a
series of benchmark data. The SST k-w turbulence model has been
utilized. The steady-state simulation is performed around a HAWT blade
using multiple reference frame. It is seen that torque increases with an
increase in wind velocity and decreases with an increase in pitch angle.
The optimum pitch angle is obtained for maximum power generation.
