Abstract

A description is given of the general aerodynamic features of the wind turbine. The complexity of the wake and the difficulties in adequately modelling the flow mean that full scale measurements are essential for its further development. Pulsed laser sheet velocimetry has been used in obtaining instantaneous flow field measurements around wind turbine blades. Wake measurements have also been obtained. Wind tunnel experiments are described in which a pulsed laser was synchronized with the turbine rotation in order to obtain phase sampled measurements. The estimation of derived quantities, such as angle of attack and circulation, is discussed. Procedures and techniques being adopted in outdoor tests are described.
