The blade design of the vertical axis wind turbine was previously designed according to the horizontal axis design method based on the leaf theory. However, since the vertical axis wind turbine is more complex than the horizontal axis and is a typical large separation unsteady flow, it is not suitable for analysis and design using the leaf element theory. Therefore, the design method of the vertical axis wind turbine blade has been changed.
The H-type wind turbine used in the vertical axis wind turbine can obtain quite good starting performance as long as the airfoil and the mounting angle are properly selected. According to the wind tunnel test of the vertical axis wind turbine, the starting wind speed of the H-type wind turbine It only needs 2m/s, which is better than the horizontal axis wind turbine mentioned above.
The blades of the vertical axis wind turbine are much better than the horizontal axis during the rotation. Because the inertial force and the direction of gravity are always the same, they are subjected to a constant load, so the fatigue life is higher than the horizontal axis. The wind wheel is long. At the same time, the generator of the vertical axis can be placed on the lower part of the wind wheel or on the ground for easy installation and maintenance.www.titanwindturbine.com
