Abstract
A combustor assembly for a turbomachine includes a combustor housing defining a combustion chamber. The combustor housing includes an inlet portion, an outlet portion, and an axial axis extending between the inlet portion and the outlet portion. A first annular plenum is arranged at the inlet portion. The first annular plenum includes a first inlet and a first outlet. A second annular plenum radially spaced from the first annular plenum is arranged at the inlet portion. The second annular plenum includes a second inlet, a second outlet, a vortex inducing member arranged between the second inlet and the second outlet, and a fuel outlet. The second outlet includes a pre-filming surface that forms an annular ring of fuel that enters the second annular plenum through the fuel outlet and passes from the second annular plenum into a swirling fluid passing through the first outlet and the second outlet.
