Abstract
The effect of blade number to the performance on cross flow wind turbines was studied by Laminar Flow analysis. In this study, cross flow turbines include Savonius turbine. The equations are discretized by Finite volume method for space and Fractional step method for time. Turbine blade is thin and arc shape. Other important parameters are chord length, camber and setting angle of blades. The following are conclusions of analysis. Two blades turbine produce highest power coefficient, and four blades turbine produces lowest power coefficient. Suitable parameters for each blade number were clarified.
