Abstract
A fuel injector and mini-mixer system includes a mixing element tube configured to mix air and fuel prior to injecting the air and fuel into a combustor, an injector positioned within the mixing element tube, the injector being configured to inject a fluid into the mixing element tube, one or more air inlet slots positioned on one or more sides of the injector, one or more fuel injection holes configured to inject fuel into the mixing element tube, and one or more delta wing vortex generators positioned within an internal wall of the mixing element tube, the one or more delta wing vortex generators configured to generate a vortex pair that accelerates the mixing of air and fuel injected into the mixing element tube. Additional air slots can be provided downstream of the delta wing vortex generators to energize the vortex pair or lift fuel away to prevent flameholding.
