Title: Apparatus for premixing in a gas turbine engine

Abstract

An apparatus for mixing fuel with oxidizing agent is disclosed comprising an outer body and an inner body. The outer body has an interior surface extending between an inlet end toward an outlet end. The interior surface includes a first plurality of openings. The inner body has an exterior surface extending between the first end and the second end of the inner body. The exterior surface of the inner body includes a second plurality of openings. At least a portion of the exterior surface of the inner body is positioned within the outer body to define a mixing channel between the exterior surface of the inner body and the interior surface of the outer body. In one form the first and second plurality of openings substantially longitudinally span at least one of the outer body and the inner body. In another form the first and second plurality of openings are substantially radially oriented. In yet another form the first and second plurality of openings are offset from one another.
