title = "Power augmentation of horizontal axis wind turbine by Mie (tip) vane: Velocity distribution around tip of HAWT blade with and without Mie (tip) vane",
abstract = "Power augmentation and velocity measurements in the wake of a HAWT with Mie (tip) vane (a tip device on the main blade) are presented. The maximum Cp with Mie (tip) vane is 15 percent larger than that without Mie (tip) vane. Power augmentation, caused by Mie (tip) vane is mainly due to the reduction of tip vortex and the diffuser effect by Mie (tip) vane. The effects of Mie (tip) vane are quantitatively verified by the velocity distributions around the tip of the main blade. The velocity distribution was measured by three-dimensional hot wire probes, which measured the axial, radial and tangential velocity components. The circulation distributions along main blade with Mie (tip) vane and without Mie (tip) vane were obtained from the measured velocity distributions. A strong reduction of calculated bound vorticity is found on the main blade without Mie (tip) vane, whereas the bound vorticity persists on the main blade tip with Mie (tip) vane.",
