Abstract
An apparatus is provided for a turbine engine. This turbine engine apparatus includes a fuel injector nozzle extending axially along an axis to a nozzle tip. The fuel injector nozzle includes an inner fuel passage and an outer fuel passage. The inner fuel passage extends axially within the fuel injector nozzle to an inner passage outlet at the nozzle tip. The inner passage outlet is formed by an inner divergent surface. The inner divergent surface is angularly offset from the axis by a first acute angle. The outer fuel passage extends axially within the fuel injector nozzle to an annular outer passage outlet at the nozzle tip. The annular outer passage outlet is formed by an outer divergent surface. The outer divergent surface is angularly offset from the axis by a second acute angle that is greater than the first acute angle.
