ABSTRACT:
Aspects of the invention relate to a system and method for introducing fuel to the flow of air along a surface upstream of a combustion area. Fuel injectors can be used to deliver fuel to the air flow at or near the boundary layer of the air flow. The fuel injectors are ideally located substantially outside of the flow path. Many benefits can be realized by keeping the injectors out of the flow path including avoidance of potential excitations and smaller pressure drops in the flow. The potential of flame from the combustion area traveling upstream to the fuel injector can be minimized by creating a disturbance in the boundary layer of the flow downstream of the fuel injectors. Such disturbances can be achieved by placing a turbulence generator in the boundary layer. The turbulence generator can be a surface protrusion or a fluid cross-flow.
