Abstract: A hot gas path duct or unibody liner for a gas turbine includes a main body having a forward end and an aft end. The main body defines a cross-sectional flow area and an axial flow length that extends between the forward end and the aft end. The main body further defines a fuel injection portion disposed downstream from the forward end and upstream from the aft end. The cross-sectional flow area decreases along the axial flow length between the forward end and the fuel injection portion and increases along at least a portion of the axial flow length downstream from the fuel injection portion.

Abstract: An aft frame assembly has a main body with an upstream facing surface, a downstream facing surface, a radially outer facing surface and a radially inner facing surface. Feed hole inlets are located on the upstream facing surface and radially outward of the outer sleeve so that the feed hole inlets are located to receive input from a high pressure plenum. The feed hole inlets are coupled to cooling channels that pass through the main body. Microchannels are formed in or near the radially inner facing surface and the downstream facing surface. The cooling channels are connected to and terminate in the microchannels. Exit holes are connected to the plurality of microchannels, and the exit holes are located radially outward of the transition piece and radially inward of the outer sleeve. The exit holes are located to exhaust into the cooling annulus.
