A CFD Study of Wind Turbine Aerodynamics

Wind turbines use the kinetic energy of the wind and convert it to mechanical energy. This is then used to produce electricity, grinding of grain or pumping of water (windmills, wind pumps). There are two types of wind turbines, horizontal and vertical. Vertical axis wind turbines (VAWT) have the rotor shaft vertically.
