This project studies vertical axis wind turbines to be mounted on the roofs of residences and public buildings. Vertical axis wind turbines were tested in the WPI closed circuit wind tunnel with different blade numbers, blade configurations, enclosures, and blade airfoil shapes to determine which variations could improve the performance of the turbine. Experiments concluded that enclosures increase the rotational velocity of the vertical axis wind turbines. The turbines with airfoil blades performed worse than the flat- plate blade turbines. The airfoil turbines did not have a linear relationship with the wind speed and in some ranges of wind speed, the rotational speed and wind speed were negatively related.
