Claim Text:
1. A method of assembling a turbine assembly comprising: coupling a fuel nozzle to a transition nozzle, the transition nozzle including a liner defining a combustion chamber therein and a wrapper circumscribing the liner such that a cooling duct is defined between the wrapper and the liner; coupling a cooling fluid source in flow communication with a cooling fluid inlet that supplies a cooling fluid to the cooling duct; coupling the cooling duct in flow communication with a cooling fluid outlet that is defined in the wrapper and receives cooling fluid discharged from the cooling duct, the cooling fluid outlet configured to direct a flow of the cooling fluid out of the cooling duct; coupling a rib between the liner and the wrapper; extending the rib completely around the combustion chamber such that a pair of axially-spaced cooling channels are defined in the cooling duct, wherein the pair of axially-spaced cooling channels include a first cooling channel and a second cooling channel that each circumscribe the combustion chamber such that the rib separates the first cooling channel from the second cooling channel; and defining a flow communication port in the rib that enables cooling fluid to flow from the first cooling channel into the second cooling channel through the flow communication port prior to being discharged into the cooling fluid outlet.
