Experimental Analysis of Near andTransitional Wind Turbine Wake Using Stereo Particle Image Velocimetry

For a wind turbine, the flow downstream of the turbines (wake) is influenced by the power extraction process. This causes a momentum deficit behind the rotor, resulting in lower velocities in the wake than the free-stream velocity. Wind turbines in a wind farm are likely to operate in the wakes of upstream turbines. This drops the power...
