Abstract
A fluidic oscillator is relatively short in length (under about 2.5 W where 'W' is the width of the power nozzle) and has a leaky splitter located proximate the center of the outlet flare so as to divide the outlet into essentially two alternating slug flows. The floor and/or ceiling of the oscillator diverge between about six degrees and ten degrees to allow the jet stream to expand and thereby avoid creating a back pressure to control ports. When used as a windshield defrost/defog nozzle, vanes forming part of the leaky splitter are laterally shifted so that the largest opening is on the driver side and the smaller opening is on the passenger side so as to direct more defrost energy towards the driver's side.
