Title: Compact multi-residence time bundled tube fuel nozzle having transition portions of different lengths

Abstract

A fuel nozzle includes a first plate, a second plate axially spaced from the first plate, a shroud extending between the first plate and the second plate, thereby defining a plenum. Tubes extend through the first plate, the plenum, and the second plate. An inlet of each tube is defined through the first plate, and an outlet of each tube is located downstream of the second plate. The tube inlets have a first size, the tube outlets have a second size different from the first size, and the walls defining the tubes have a transition portion between the inlet and the outlet. The transition portion has an axial length from the fuel injection port to a location having a diameter of the second size. The transition portion of a first tube extends a first axial length and the transition portion of a second tube extends a different second axial length.
