A flow conditioning system for a duct. The flow conditioning system includes a preconditioner that modifies upstream fluid flow that is maldistributed, providing predictable downstream flow to fluid flowing within the duct. The directional flow conditioner also includes a stationary flow geometry structure downstream of the preconditioner. The stationary flow geometry structure further conditions the upstream fluid flow from the preconditioner to provide a downstream flow with a substantially uniform flow profile. The flow conditioning system transforms upstream fluids having a maldistributed flow profile such as may be caused by a component, structure or obstruction within the duct to a substantially uniform flow profile downstream of the flow conditioning system within the available axial duct length so that the fluid may interact efficiently with equipment such as heat exchangers positioned within the duct downstream of the flow conditioning system.

A combustion liner for use in a combustor assembly is provided. The combustion liner includes a side wall that defines a combustion chamber having a main flow axis extending therethrough. The combustion chamber channels a flow of combustion gas therethrough along a mixer swirl flow axis oriented obliquely relative to the main flow axis. The combustion liner also includes film cooling holes defined within the side wall. The film cooling holes are configured to discharge a pressurized fluid jet into the combustion chamber, and arranged in at least a first row and a second row positioned a first distance from the first row. The film cooling holes are arranged such that, when mixed with the flow of combustion gas, the pressurized fluid jet discharged from film cooling holes in the first row is directed along a discharge flow axis misaligned from film cooling holes in the second row.

Exhaust apparatus for exhausting 'dirty' exhaust gases accept a core flow of such exhaust gases and combine that with an annularly-surrounding 'rooftop' flow of ambient air for diluting the exhaust gases as well as expelling the diluted flow in a forcibly expelled plume in order to ensure that the &#x201c;effective&#x201d; expulsion distance of the expelled diluted flow is at least the physical length of the exhaust apparatus plus the gains gotten from efflux velocity and flowrate.

A mixed flow fan wheel has a convex hub, an axially-spaced away concave annular shroud, and a plurality of angularly distributed blades extending between and interconnecting the hub and shroud, all which cooperatively define a plurality of inter-blade flow channels. Each has a pressure surface and spaced suction surface extending not only between spaced inlet and discharge edges but also, crosswise thereto, spaced hub-side and shroud-side edges. Each discharge edge is convex relative a center of geometry of the blade therefor. Each inter-blade flow channel originates in a generally rectangular shape between flanking inlet edges and terminates in another generally rectangular shape between flanking discharge edges, with a procession of gradations of generally rectangular shapes forming a progressive transition therebetween. Moreover, each inter-blade flow channel twists or corkscrews from inlet thereof to the discharge.
