Augmentation of Power Output of Axisymmetric Ducted Wind Turbines by Porous Trailing Edge Disks

This paper presents analytical and experimental results that demonstrated that the power output from a ducted wind turbine can be dramatically increased by the addition of a trailing edge device such as a porous disk.

Description
Summary:This paper presents analytical and experimental results that demonstrated that the power output from a ducted wind turbine can be dramatically increased by the addition of a trailing edge device such as a porous disk. In addition, the trailing edge device can be designed to be geometrically adaptable, allowing the turbine to spin up at low wind speeds and providing relief from aerodynamic loads at high wind speeds.
