Abstract: A fluid disperser is provided for dispersing a first fluid into a moving eam of a second fluid. After the first fluid is pressurized to at least twice the pressure of the second fluid, the first fluid is passed through a throat that increases the flow velocity of the first fluid to supersonic. A fluidic oscillator, coupled to the output of the throat, has a central axis of symmetry, a first end by which the first fluid enters the oscillator and a second end by which the first fluid exits the oscillator. The oscillator includes two opposing walls that diverge symmetrically about the central axis from the first to the second end at an angle of divergence relative to the central axis that causes the first fluid entering the first end to attach to either of the two opposing walls and continue therealong to the second end.
