An ultrasonically enhanced continuous flow apparatus for injection of liquid fuel into a continuous fuel combustor and a method of improving continuous flow fuel combustors by the application of ultrasonic energy to a pressurized liquid fuel exiting an orifice is disclosed. The apparatus includes an injector or die housing which in part defines a chamber adapted to receive a pressurized liquid and a means for applying ultrasonic energy to a portion of the pressurized liquid. The die housing further includes an inlet adapted to supply the chamber with the pressurized liquid, and an exit orifice defined by the walls of an injector tip or die tip. The exit orifice is adapted to receive the pressurized liquid from the chamber via a vestibular cavity and pass the liquid out of the die housing. When the means for applying ultrasonic energy is excited, it applies ultrasonic energy to the pressurized liquid without mechanically vibrating the die tip. The method involves supplying a pressurized liquid to the foregoing apparatus, applying ultrasonic energy to the pressurized liquid while not mechanically vibrating the die tip while the exit orifice receives pressurized liquid from the chamber, and passing the pressurized liquid out of the exit orifice in the die tip.
