Abstract

A dual-fuel fuel nozzle 100 includes a centerbody 102 that at least partially defines an air plenum 130 therein. A tip body 132 is disposed at a downstream end of the centerbody 102. The tip body 132 includes an upstream side 134 that is axially spaced from a downstream side 136. The downstream side 136 defines a circular slot 138 and a circular recess 156 that is positioned radially inwardly from the circular slot 138. The circular recess 156 includes a floor 158 and a side wall. The floor 158 defines an insert opening and the side wall defines an annular groove 162 that includes an undercut surface 164. The tip body 132 further defines a plurality of orifices 170 annularly arranged around the insert opening radially inward from the side wall of the circular recess 156. Each orifice 170 includes an inlet 172 that is in fluid communication with the air plenum 130 and an outlet 174 that is oriented towards the undercut surface 164.
