Abstract: A fuel system for a turbine engine. The fuel system includes a fuel/air mixer configured to mix air with fuel in a controlled fuel/air ratio, the fuel/air mixer having a body defining a chamber. The fuel system also includes a fuel nozzle in fluid communication with the fuel/air mixer. The fuel nozzle is configured to inject fuel into the chamber of the fuel/air mixer. The fuel nozzle is located forwardly relative to the body of the fuel/air mixer so that a jet-in-crossflow of the fuel is angled relative to a foot of the body of the fuel/air mixer.

Abstract: A gas turbine combustor includes a main mixer for providing an air flow to mix with a fuel flow in a combustor. The main mixer includes an annular mixer body, a plurality of mixer vanes located circumferentially around the annular mixer body, and a plurality of wedges extending radially outward from each of the plurality of mixer vanes. At least one of the wedges includes serrations. The air flow through the main mixer enters the main mixer at a leading edge of the mixer vane, flows over the plurality of wedges, and exits the mixer vanes at a trailing edge of the main mixer. The wedges create vortices in the air flow to provide a uniform fuel-air flow.
