VORTICITY REDUCING COWLING FOR A DIFFUSER AUGMENTED WIND TURBINE ASSEMBLY

摘要

A vorticity reducing cowling for a diffuser augmented wind turbine assembly is provided. The diffuser augmented wind turbine assembly includes a shroud, a wind turbine disposed within the shroud, and a diffuser coupled to an outlet of the shroud. The wind turbine includes a wind turbine housing and a plurality of blades rotatably disposed within the wind turbine housing, wherein the plurality of blades providing a swept area. The cowling comprises a body disposed upstream of the plurality of blades. The body includes an inlet end defining a first opening, the first opening having a first area. The body includes an outlet end defining a second opening, the second opening having a second area that is less that the first area. The second area is less than the swept area of the plurality of the blades.
