1. A fluid nozzle comprising:
a first fluid circuit;
a second fluid circuit spaced apart from the first fluid circuit;
a fuel circuit defined between the first and second fluid circuits and between a first fuel circuit wall and a second fuel circuit wall; and
a ring-shaped permeable barrier that forms a complete annulus between the first and second fuel circuit walls, wherein the ring-shaped permeable barrier is configured and adapted to provide a controlled resistance to fuel flow, and wherein the first and second fuel circuit walls each define at least a portion of the boundary of the fuel circuit upstream from the ring-shaped permeable barrier.
