Abstract:
A system for coalescing bubbles in the wake of a structure piercing the surface of the water, comprising:a first plurality of acoustic sources mounted to said structure for producing a corresponding first plurality of plane waves angled in a first direction, said first plurality of acoustic sources spaced along at least one plane that pierces the surface of the water; anda second plurality of acoustic sources mounted to said structure for producing a corresponding second plurality of plane waves angled in a second direction, said second plurality of acoustic sources spaced along said at least one plane that pierces the surface of the water, wherein said first plurality of plane waves and said second plurality of plane waves intersect to create a plurality of standing wave fields both above and below the surface of the water, wherein:said first direction is oriented downward with respect to the surface of the water;said second direction is oriented upward with respect to the surface of the water; andsaid second plurality of acoustic sources being interleaved with said first plurality of acoustic sources.
