Abstract:
A standing wave pump comprising:a pump housing for holding a fluid to be pumped;said pump housing having a first end and a second end;said pump housing having an outlet and an inlet;wave generating means for establishing standing planar compression waves in said fluid in said pump housing;said wave generating means comprising a first reflective emitter and a second reflective emitter;said first reflective emitter being located at said first end of said pump housing;said second reflective emitter being located at said second end of said pump housing in opposing relationship with said first reflective emitter;wherein said first reflective emitter generates a first planar pressure wave of a first wavelength and a first energy amplitude in said fluid,said first energy amplitude being sufficient to reach and be reflected by said second reflective emitter;and wherein said second reflective emitter generates a second planar compression wave of a second wavelength and a second energy amplitude in said fluid;said second energy amplitude being sufficient to reach and be reflected by said first reflective emitter;and wherein said second reflective emitter is separated from first reflective emitter by a distance equal to an integer multiple of half said first wavelength or an integer multiple of half said second wavelength;whereby said first and second planar compression waves are generated and reflected simultaneously, thereby generating a standing compression wave with a third energy amplitude;said third energy amplitude being greater than either said first energy amplitude or said second energy amplitude;said standing compression wave having one or more pressure nodes therein; andsaid standing compression wave having one or more pressure antinodes therein.
