Blade Element

In order to increase the performance of lift-type wind turbine, at the minimal torque value area, two interfere air flow is used to rebuilding the air flow. Based on multiply stream-tubes model, the effect of interfere air on promotion performance of blade element are studied. the results prove the interfere air method does greatly arise the torque, the attack angle of blade element at 0°~15 and 165°~180°azimuth angle, and promote the torque of single blade wind turbine with two or three blades. The paper provides a new way for vertical axis wind turbine designing and application.
