Abstract
An apparatus includes a chamber and an intake device configured to control a flow of fluid into the chamber. The fluid comprises particles; a resonance device is configured to resonate the chamber to provide an acoustic standing wave within the chambers. The frequency of the standing wave is selected to cause particles above a specific size to collect at a node of the standing wave.
Claims18
An apparatus, comprising:
- a chamber;
- an intake device configured to control a flow of fluid into the chamber, wherein the fluid comprises particles;
- and
- a first resonance device located at an end of the chamber and configured to resonate the chamber to provide an acoustic standing wave within the chamber,
- wherein a frequency of the standing wave is selected to cause particles above a specific size to collect at a node of the standing wave,
- wherein the intake device comprises a conduit and a second resonance device located at an open end of the conduit,
- wherein the conduit extends perpendicularly from a side of the chamber and is in direct fluid connection with the chamber at the side of the chamber, and
- wherein the conduit comprises an absorptive material disposed between the second resonance device and the chamber.

A method, comprising:
- controlling a flow of fluid from a conduit into a chamber, wherein the fluid comprises particles;
- and
- resonating the chamber with a first resonance device located at an end of the chamber to provide an acoustic standing wave within the chamber,
- wherein a frequency of the standing wave is selected to cause particles above a specific size to collect at a node of the standing wave,
- wherein the controlling of the flow of fluid from the conduit into the chamber comprises controlling the flow with an intake device comprising a second resonance device,
- wherein the controlling of the flow of fluid from the conduit into the chamber comprises controlling the fluid to flow perpendicularly in the conduit from the flow of fluid in the chamber, and through a side opening of the chamber, and
- wherein the controlling of the flow of fluid from the conduit into the chamber comprises controlling the fluid to flow around an absorptive material disposed between the second resonance device and the chamber.
