Effect of freestream turbulence on the coherent dynamics of a wind turbine wake
The wake of a model wind turbine exposed to freestream turbulence (FST) with a variety of turbulent characteristics is studied through Particle Image Velocimetry experiments. The FST cases spanned turbulent intensities (T_i) in the range 1% < T_i < 13.1 % and integral length scales (L_v) in the range 0.01D < L_v < 0.11D (where D is the diameter of the turbine model)}. Increasing T_i and L_v in this range resulted in an earlier breakdow…
