411 Experimental Study on Optimized Guide Vanes of Vertical Axis Type of Cross Flow Wind Turbines

Abstract

In this paper, aerodynamic characteristics of the cross flow type of wind turbine were studied experimentally by using sub-scale model, considering the effect of guide vanes and its arrangement. The aerodynamics characteristics of the turbine for wind flow direction were discussed by reference to the power and the torque coefficients correlation of tip speed ratio for various combinations of approaching optimized guide vanes number and optimal configuration.
