Wakes of both a stand-alone wind turbine and 3 wind turbines placed in a row is analysed using a numerical method where a three-dimensional Navier Stokes solver is combined with an actuator line technique. The computations on the single turbine indicate the appearance of low frequency fluctuations of the wake similar to what is observed behind a disc. Furthermore, the computations on a row of turbines demonstrate that downstream turbines might experience the distinct tip vortices formed in the wake of upstream turbines. Results also show that placing the turbines too closely can significantly reduce the produced power.
