Diffuser augmented wind turbines are described below. In an embodiment a wind turbine diffuser has an expanded outlet area where the diffuser outlet area is greater than it's cross sectional area. In an example,the diffuser may be formed of one or more diffuser rings, at least one of which may form a turbine cowling. Each diffuser ring may have an inlet area that is smaller than the outlet area of the directly upstream ring. In an example the portion of an upstream ring outlet which is not occluded by the downstream ring may form a diffuser outlet such that the total outlet area of the diffuser is larger than the cross-sectional area. In another example,the diffuser may comprise at least one diffuser ring and one or more suction slots that are each connected to a vent,which allows air to be removed from the diffuser system. |
