Little is known about the aerodynamics of biplane wind turbine blades. Even more fundamentally, the two-dimensional aerodynamics of thick biplane airfoils are not well-understood. Supported by the Link Foundation Energy Fellowship, this research has sought to develop a better understanding of these aerodynamics through wind tunnel experiments and computational fluid dynamics. An understanding of biplane aerodynamics is a key step towards the commercial implementation of biplane wind turbine blades. These designs could enable larger turbines designs, ultimately reducing the cost of wind-generated electricity and helping to displace conventional means of electricity generation.
