N2 - In this paper, wake interaction between two wind turbines <br/>is analyzed using experimental and numerical <br/>approaches. Full-scale wake measurements are <br/>conducted at Tjæreborg wind farm and are obtained <br/>using a continuous wave lidar mounted on the back <br/>of the nacelle of a 2MW NM80 turbine. Numerical <br/>analyses are conducted for two double wake cases <br/>characterized by different turbine spacing, using the <br/>in-house EllipSys3D flow solver. Large Eddy Simulation <br/>and Actuator Line technique are used for modeling <br/>the rotor and the flow field. 10-minute average <br/>streamwise velocity and turbulence level are compared, <br/>and good agreement is seen between the <br/>measurements and the computations despite of a <br/>lateral offset and other discrepancies due to uncertainties <br/>on the measured inflow conditions and lidar <br/>mounting alignment.
