Aerodynamic and aeroacoustic simulations were conducted for a small wind turbine. Simulations were conducted for rotor only and full wind turbine configurations. Predicted turbine power and acoustic spectra agree well with field measurements. Presence of the tower decreases the wind turbine power output prediction. Presence of the tower leads to modifications of the acoustic spectra above 300 Hz.
