S051034 Numerical Simulation for the Foil Section of Cross Flow type Wind Turbine

Abstract

Some foil sections of cross flow wind turbines were simulated by Laminar Flow analysis. The equations are discretized by Finite volume method for space and Fractional step method for time. In this study, blade number is 16 and chord length is 15% of diameter. Blade set angle is 45degree and its camber is 15% of chord. Important parameters are thickness and the edge shape of blade. The following are results of analysis Best shape was outer- wedge type and round edge was not good in the standpoint of maximum power. Thickness of blade decrease maximum power.
