초록

A combustor dome assembly having a venturi and an auxiliary wall concentric with the venturi to provide an annular passage for channeling or directing a high velocity air jet from a swirler to a combustion chamber associated with a downstream end of the venturi, thereby facilitating the atomization of a film of water flowing along an inner surface of the venturi and out of the downstream end. In an alternative embodiment, a deflector is used (instead of the auxiliary wall) to direct the air flow towards the downstream end. The downstream end of the ventu...
