Aerodynamic Measurements on a Horizontal Axis Wind Turbine in a Laboratory Wind Tunnel
(0) A scaled fixed-pich variable speed horizontal axis wind turbine (HAWT) model which is designed for non-gridconnected wind power system was experimentally studied.The experiment was carried out in a laboratory wind tunnel.With pressure acquisition system and a five-hole probe,details about flow fields in the near wake of the turbine blade were obtained.The result shows that,for a fixed-pich variable speed HAWT,the measured tangential velocity is almost negative,which means in wake area the direction of flow is counterclockwise to the rotor rotation direction.When at ? ? 4.48,the radial velocity does not change a a lot at different radial positions.And along the downstream direction,the radial velocity decreases.However when ? ?10.04 the radial velocity is increasing along the radial direction,especially at the blade tip area.
