ABSTRACT:
An improved efficiency flow enhancement method and system is provided for a duct system downstream of blading in a turbomachine, the system comprising the blading, a duct leading from the blading, two or more passages defined at least in part by partitions which take flow from within the duct, or from across its outlet, or from within four duct widths downstream of its outlet, the partitions defining at least partially separated flow passages intended for flows leaving the expanding duct of generally different mechanical energy, one or more zones of significant pressure drop for the flows of higher energy, one or more passages of comparatively less pressure drop for the passages with flows of lower mechanical energy, one or more zones where the flows are rejoined, and an outlet.
