Abstract
A fuel shroud assembly () into which fuel () is injected for mixing with an air stream () in a fuel manifold. The shroud assembly () comprises a plurality of parallel fuel scoops () each receiving the injected fuel (). The fuel stream () flows through each scoop (), exiting at an open scoop end (A). The air stream () flows between scoops, creating a shear region proximate each scoop end (A) where the fuel exits. The shear causes mixing of the air () and the fuel () streams, wherein the degree of mixing is not dependent on the momentum ratio of the air () or fuel () streams.
