Abstract
A fuel nozzle for a gas turbine engine combustor includes a fuel nozzle assembly including an inflow tube disposed along and a nozzle axis, the inflow tube defining an inner air passage and a liquid swirler concentrically disposed about the inflow tube. The liquid swirler includes a liquid swirler inner wall, a liquid swirler outer wall having a liquid swirler outer wall end portion at a downstream-most position and angled radially inward toward the nozzle axis, and an annular liquid passage defined therebetween. The fuel nozzle assembly further includes a radial air swirler (RAS) concentrically disposed about the liquid swirler outer wall, the RAS including an RAS inner wall, an RAS outer wall having an end cap at a downstream-most position, and an annular gas passage defined therebetween. The end cap has a radiused inner surface and a contoured outer surface. The fuel nozzle assembly further includes a guide swirler disposed concentrically about the RAS outer wall, the guide swirler comprising an annular air passage angled radially inward toward the nozzle axis.
