Short summary
The energy capture of a wind turbine can be improved by completely surrounding it with an airfoil-shaped duct. This paper describes a new modeling strategy used to design an experimental 2.5 m ducted turbine, tested at the University of Waterloo wind turbine test facility. The wind tunnel data validated the predicted performance, indicating that the ducted turbine produced more than twice the power output of a conventional turbine design of the same size. Design implications are also discussed.
