Abstract
An apparatus is provided for a turbine engine. This apparatus includes a fuel-air mixer, and the fuel-air mixer includes a mixer outlet, an annular inner passage, an air swirler, an annular fuel passage and a fuel swirler. The annular inner passage extends axially along an axis within the fuel-air mixer. The annular inner passage includes an inner passage downstream section and an inner passage upstream section fluidly coupled with the mixer outlet through the inner passage downstream section. The inner passage downstream section radially tapers and diverges radially outward away from the axis as the annular inner passage extends axially towards the mixer outlet. The air swirler is disposed with the inner passage upstream section. The annular fuel passage circumscribes the annular inner passage and extends axially within the fuel-air mixer to the inner passage downstream section. The fuel swirler is disposed with the annular fuel passage.
