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 sign...


A flow enhancement system for exhaust in the combination of: a generally tubular sectioned diffuser duct for discharging gas along an axis having a smaller forward end for receiving gas flow and a larger discharge end for discharging the gas flow, the tubular sectioned diffuser duct having a divergence exceeding 7°with respect to the axis of the generally tubular sectioned diffuser duct; a central gas flow path having an inside flow boundary adjacent the axis, an outside flow boundary remote from the axis, and the central gas flow path defined between th...
