Abstract
The paper describes a wind-tunnel study of the wake dynamics of an operatio nal, horizontal-axis wind turbine. The behaviour of the vorticity trailing from the turbine blade tips and the effect of was interference on wake deve lopment were considered. Laser sheet visualisation (LSV) techniques were us ed to measure the trajectories of the trailing vorticity under various cond itions of turbine yaw and blade azimuth. Selected results obtained in the e xperimental study were compared with the predictions of a prescribed wake m odel and are being used in the further development of the method.
