Abstract
A nozzle is adapted to receive an ultrasonic transducer. The nozzle includes a cylindrical plenum chamber. An annular passageway circumscribes the plenum chamber. A porous material forms the annular walls of the plenum chamber and separates the plenum chamber from the passageway. The plenum chamber fluidly communicates with the passageway through the porous material. The passageway fluidly communicates with a supply line that, in turn, fluidly communicates with a pump that supplies water. The plenum chamber has a circular exhaust orifice for the exhaust of water from the nozzle. The plenum chamber contains an unobstructed forming space to facilitate the forming of ultrasonic waves. The diameter of the plenum chamber divided by the diameter of the exhaust orifice is a quotient of at least three. The periphery of the exhaust orifice is an edge formed by the intersection of two concentric surfaces of revolution, each of which is symmetrical about the centerline of the plenum chamber and lies at a respective angle with respect to the centerline.
