Abstract
Method and system for uniformly spacing particles in a flowing system comprising suspending particles in an elongated fluid filled cavity; exposing said cavity to an axial acoustic standing wave field, wherein said axial acoustic standing wave field drives said particles to nodal and anti-nodal positions along the center axis of said cavity to result in uniformly spaced particles; and focusing said particles to the center axis of said cavity.
Claims10
A method of uniformly spacing particles in an open flowing system comprising:
- a) suspending particles in an elongated fluid filled cavity and flowing said fluid;
- b) exposing said cavity to an axial acoustic standing wave field parallel to the direction of flow, wherein said axial acoustic standing wave field drives said particles to nodal and anti-nodal positions along the center axis of said cavity to result in uniformly spaced particles;
- and
- c) focusing said particles to the center axis of said cavity.
