Abstract
Method and computer-readable model for additively manufacturing a ducting arrangement () for a gas turbine engine are provided. Ducting arrangement () may include a duct () to be fluidly coupled to receive a cross-flow of combustion gases from a main combustion stage. Duct () includes a duct segment () with an expanding cross-sectional area () where one or more injector assemblies () are disposed. Injector assembly () includes one or more reactant-guiding structures () arranged to deliver a flow of reactants to be mixed with the cross-flow of combustion gases. The ducting arrangement is effective to reduce total pressure loss while providing an effective level of mixing of the injected reactants with the passing cross-flow. Respective duct components or the entire ducting arrangement may be formed as a unitized structure, such as a single piece using a rapid manufacturing technology, such as 3D Printing/Additive Manufacturing (AM) technologies.
