Downstream wind flow path diversion and its effects on the performance of vertical axis wind turbine

In the present experimental study efforts have been made to analyse path diversion effect of downstream wind flow on performance of vertical axis wind turbine (vawt). for the blockage of downstream wind flow path at various linear displaced positions,a normal erected flat wall,semi-circular and cylindrical shapes were tested for path diverting geometries. performance of vawt in terms of improved rotor speed up to 45% was achieved. © 2015,pcsir-scientific information centre. all rights reserved.
