Large-eddy simulation study of effects of clearing in forest on wind turbines
Paper in proceedings, 2018

The setup of Ryningsnäs in Sweden is simulated with wind blowing from the south. The inlet boundary planes are used from a precursor that has a length of 5000m to avoid streaks. For the second wind turbine the current clearing has the highest electrical power. In the extended clearing the estimated power is higher than in the homogeneous forest but FAST estimates the opposite. The second turbine in the extended clearing has the lowest rotor torque and RMS values and fatigue loads of the rotor bending around the y-axis and z-axis.
