Measurement results of the wake velocity profile behind 0.6 m-diameter wind turbine in wind tunnel and 10 m-diameter wind turbine in the field are shown. The development of wind turbine wake was observed with the use of particle image velocimetry for wind tunnel measurement. From the results of wind tunnel measurement, the wake was expanded from the position where the tip vortex was almost dissipated. The wake velocity behind field wind turbine was recovered in shorter distance than those for the turbine in wind tunnel measurement. The wake area was sifted toward radial direction related to wind turbine rotational direction. The wake velocity at lower half area below rotor axis was not much recovered by the effect of tower compared to those at upper half area above rotor axis.
