Abstract
A fuel injector arrangement for a turbine engine is disclosed. The fuel injector arrangement may have a combustion chamber, a plenum, an injector, and a premixing chamber configured to receive the injector. The premixing chamber may be at least partially disposed within the plenum and open to the combustion chamber. The premixing chamber may have at least one passageway configured to allow air from the plenum to enter and mix with fuel from the injector to form an air/fuel mixture within the premixing chamber, and a porous annular wall configured to allow air from the plenum to enter and create a lean boundary layer at the porous annular wall.
