Methods of conveying fluids and methods of sublimating solid particles
First Claim
1. A method of conveying a fluid, the method comprising:
- conveying a first fluid into a porous member along a centerline of the porous member;
conveying a second fluid into the porous member through pores of a porous wall of the porous member to form a positive flow boundary layer substantially along an inside of the porous wall and to at least reduce contact of the first fluid with the porous wall;
conveying both the first fluid and the second fluid out of the porous member.

Abstract
A heat exchanger and associated methods for sublimating solid particles therein, for conveying fluids therethrough, or both. The heat exchanger includes a chamber and a porous member having a porous wall having pores in communication with the chamber and with an interior of the porous member. A first fluid is conveyed into the porous member while a second fluid is conveyed into the porous member through the porous wall. The second fluid may form a positive flow boundary layer along the porous wall to reduce or eliminate substantial contact between the first fluid and the interior of the porous wall. The combined first and second fluids are conveyed out of the porous member. Additionally, the first fluid and the second fluid may each be conveyed into the porous member at different temperatures and may exit the porous member at substantially the same temperature.

7. A method of sublimating solid particles, the method comprising:
-
conveying a first fluid comprising a chemical in a solid particulate form into at least one porous member; heating the chemical within the at least one porous member to a gaseous form, heating comprising; directing a second fluid at a temperature higher than a temperature of the first fluid into the at least one porous member through pores of a porous wall of the porous member; and mixing the first fluid and the second fluid; conveying the chemical in the gaseous form out of the at least one porous member with the first fluid and the second fluid. - View Dependent Claims (8, 9, 10, 11, 12, 13)
