In this paper, wake interaction between two wind turbines is analyzed using experimental and numerical approaches. Full-scale wake measurements are conducted at Tjæreborg wind farm and are obtained using a continuous wave lidar mounted on the back of the nacelle of a 2MW NM80 turbine. Numerical analyses are conducted for two double wake cases characterized by different turbine spacing, using the in-house EllipSys3D flow solver. Large Eddy Simulation and Actuator Line technique are used for modeling the rotor and the flow field. 10-minute average streamwise velocity and turbulence level are compared, and good agreement is seen between the measurements and the computations despite of a lateral offset and other discrepancies due to uncertainties on the measured inflow conditions and lidar mounting alignment
