Resumo

In this paper, response surface methodology (RSM) based on central composite design (CCD) is applied to obtain an optimization design for the asymmetric blades geometry of a vertical axis wind turbine (VAWT). Turbine's airfoils are simulated by using computational fluid dynamics (CFD). The SST K-ω model is used to simulate turbulent flow around the asymmetric blade. The free-stream velocity is constant and the rotation speed of turbine rotor is considered 350 to 600 rpm. Results show that the maximum torque coefficient is obtained at rotation of 450 rpm.
