The present work considers an experimental investigation of wind turbine near wake by using Particle Image Velocimetry (PIV) visualization technique. The PIV technique gives a complete picture of all points at the domain under consideration. The study is focused on the effect of tip speed ratio () and Reynolds number (Rec) on the near wake characteristics. A three-blade model of wind turbine with airfoil SG 6040 16% is tested in water channel at Rec range between 1.28 ×104 and 7.68 ×104. Various tip speed ratios are tested between =2 and =12. Experiments are also performed at constant =8 and variable Rec in the range between 2.56 ×104 and 5.12 ×104. |
