ABSTRACT:
A fuel nozzle of a variety for dispensing an atomized fluid spray into the combustion chamber of a gas turbine engine. The nozzle includes a first fluid conduit extending along a longitudinal central axis from an upstream end to a downstream end portion terminating to define a primary discharge orifice, a second fluid conduit which is received coaxially over the first fluid conduit as extending along the central axis from an upstream end to a downstream end portion terminating to define a secondary discharge orifice disposed generally concentrically with said primary discharge orifice, and a third fluid conduit which is received coaxially over the second fluid conduit as extending along the central axis from an upstream first end to a downstream second end. The outer surface of the downstream end portion of the first fluid conduit and the inner surface of the downstream end portion of the third fluid conduit define therebetween a generally annular, internal mixing chamber. First and second fluid inlet ports are provided as extending along longitudinal first and second port axes in fluid communication with, respectively, the second and third fluid conduits and the mixing chamber. The second inlet port is disposed angularly to the first inlet port such that the second port axis intersects the first port axis within the mixing chamber to define an impingement locus for the admixing of a first fluid from the second fluid conduit and a second fluid from the third fluid conduit.
