Abstract turbine could increase the output power [4] This work is focused on optimization of wind turbine blade profile by two dimensional flow field analysis. A multi-objective response surface technique with computational fluid dynamics (CFD) was performed on two dimensional wind turbine blade airfoil. Based on the data of National Renewable Energy Laboratory (NREL) phase VI wind turbine rotor, six different airfoil (NACA xx-xxxx, Fx and E Series) were used to calculate different aerodynamic loads (lift & drag) and their effects. Commercial software ANSYS Fluent was used to evaluate the lift coefficient (C L ) and drag coefficient (C D ) at dif ferent angle of attack (α) and three different Reynolds number (Re). Statistical code JMP was used to perform the response surface and finally a discrete optimization technique was developed discrete variable and with the help of MATLAB we to find an optimal airfoil that gives satisfactory performance in optimum aerodynamic performance in a wide range of a wide range of design conditions.
