ABSTRACT:
A fuel nozzle with a ring of fuel spray orifices directing fuel jets at a fuel vortex generator having a fuel deflecting surface disposed downstream a distance from each fuel spray orifice. A mixing chamber is defined between the fuel spray orifices and the fuel deflecting surface having a surface contour oriented to deflect fuel jets into the mixing chamber in counter-rotating adjacent pairs of fuel laden vortices. An air inlet supplies air to the mixing chamber via an airflow vortex generator having an airflow deflecting surface with a surface contour oriented to deflect airflow into the mixing chamber in counter-rotating adjacent pairs of airflow vortices. A fuel-air mixture outlet downstream from the mixing chamber releases the fuel-air mixture into a combustor for ignition.
