Fluid distributors for fluid nozzles

A fuel distributor comprising:

• a first fuel circuit wall;
• a second fuel circuit wall spaced apart from the first fuel circuit wall, wherein a fuel circuit is defined between the first and second fuel circuit walls;
• 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 in the fuel circuit, 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.

A combustion assembly comprising:

• a combustor housing;
• a combustor dome positioned at an upstream end of the combustor housing;
• and
• a fluid nozzle positioned adjacent to the combustor dome, the fluid nozzle including:
• 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 fluid circuit walls, wherein the ring-shaped permeable barrier is configured and adapted to provide a controlled resistance to fluid 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.
