Abstract
Various embodiments comprise systems, methods, architectures, mechanisms or apparatus configured to separate particles of varying size within a fluid flow, or filter particles from a fluid flow, via an array of anchored-liquid drops or anchored-gas drops.
Claims18
A particle filtration apparatus, comprising:
- an array of anchored-fluid drops disposed upon a first surface having a channel for receiving therethrough a fluid flow, the array generally formed as rows and columns of fluid drops anchored via respective anchoring structures formed on said first surface and configured for obstructing proximate portions of said fluid flow, the array positioned to receive the fluid flow at a forcing angle selected to cause trapping of particles of a predefined size from the fluid flow at a fluid flow-fluid drop interface;
- wherein the anchored-fluid drops comprise anchored-liquid drops;
- wherein the fluid flow-fluid drop interface comprises an air-liquid interface and the trapped particles comprise pollutants within a flow of air.
A particle filtration apparatus, comprising:
- an array of anchored-fluid drops disposed upon a first surface having a channel for receiving therethrough a fluid flow, the array generally formed as rows and columns of fluid drops anchored via respective anchoring structures formed on said first surface and configured for obstructing proximate portions of said fluid flow, the array positioned to receive the fluid flow at a forcing angle selected to cause trapping of particles of a predefined size from the fluid flow at a fluid flow-fluid drop interface;
- wherein the anchored-fluid drops comprise anchored-liquid drops;
- wherein said array of anchored-liquid drops are disposed between said first surface and a second surface, said first and second surfaces defining therebetween said channel.
A particle separation apparatus, comprising:
- an array of anchored-fluid drops disposed upon a first surface having a channel for receiving therethrough a fluid flow, the array generally formed as rows and columns of fluid drops anchored via respective anchoring structures formed on said first surface and configured for obstructing proximate portions of said fluid flow, the array positioned to receive the fluid flow at a forcing angle selected to cause a separation of particles of different predefined sizes within the fluid flow;
- wherein the anchored-fluid drops comprise anchored-liquid drops;
- wherein the interface between fluid flow and liquid drop comprises an immiscible liquid-liquid interface.
A particle filtration method, comprising:
- disposing an array of anchored-fluid drops disposed upon a first surface having a channel for receiving therethrough a fluid flow, the array generally formed as rows and columns of fluid drops anchored via respective anchoring structures formed on said first surface and configured for obstructing proximate portions of said fluid flow, the array positioned to receive the fluid flow at a forcing angle selected to cause trapping of particles of a predefined size from the fluid flow at a fluid flow-fluid drop interface,
- wherein the anchored-fluid drops comprise anchored-liquid drops;
- wherein the fluid flow-fluid drop interface comprises an air-liquid interface and the trapped particles comprise pollutants within a flow of air.
