Abstract
The aerodynamic and acoustic characteristics of a horizontal axis wind turbine was computationally investigated. The Computational Fluid Dynamics model of the horizontal axis wind turbine was validated with experimental data for a range of wind speeds and tip pitch angles. In addition, a mesh sensitivity analysis was performed to verify a grid independent solution. Steady state simulations were performed to validate the flow behavior over the airfoil section while transient simulations were performed in order to predict acoustic noise. The acoustic noise of the rotor was predicted at locations downstream of the rotor in the wake region. Higher tip pitch angles were found to result in less noise.
