system in a gas turbine engine are provided. A reactant-guiding structure (42) may be
configured to define a curvilinear flow path (47) to route a flow of reactants from a first flow
direction (50) to a second flow direction (52) toward a cross-flow of combustion gases (60). A
cross-flow guiding structure (54) may further define a flow path (58) to route a portion of the
cross-flow of combustion gases toward an outlet side of the cross-flow guiding structure …
