Aerodynamic Analysis of Air foil in Vertical Axis Wind Turbine

The main objective of this study is to better understandings the effects of various parameters like airfoil shape/type, Reynolds number, angle of attack, wind speed on the performances of these turbines. These effects are investigated on a straight bladed vertical axis wind turbine which leads to variations of pressure distribution on upper and lower surface of the blade section. The work can be started by Direct Design method of specified section geometry and the calculation of pressure and performance by theoretically. This could be compared with numerically by using SOLID WORKS as modelling and ANSYS CFX as solver for NACA 00xx, NACA xxxxx at different angle of attack and different velocities. From these the pressure and force distribution of airfoil section NACA xxxxx and NACA 00xx were calculated and the power coefficient of the former one increased than later one. This would leads changing of airfoil thickness may cause the power coefficient.
