Abstract
A micromixer of a gas turbine has a plurality of tubes each having an inlet and an outlet for receiving a flow and dispersing the flow to a combustor. At least some of the tubes have a liquid fuel injector, and the liquid fuel injector projects into one of the tubes. The liquid fuel injector has a ramped upstream surface and two converging side surfaces. The ramped upstream surface compresses the flow passing thereover, and a top surface of the liquid fuel injector comprises a liquid fuel outlet.
