Vertical axis wind turbine with optimized blade profile |
摘要 |
A high efficiency vertical axis wind turbine includes an optimized blade shape for increased torque output. The shape of the optimized profile includes a camber portion at a leading edge region of the blade with a maximum height to chord ratio (Y/C) at when the non-dimensional chord length (X/C) is approximately one third. An intermediate region follows the leading edge region and is characterized by a shallow convex region, followed by a flow reattachment surface at the trailing edge region characterized by a second concave region and a local maximum of the height to chord ratio at approximately four fifths of the non-dimensional chord length.
