Abstract

Honeycomb body interdigitating mixers have parallel cells extending along a common direction, the mixer comprising a first fluid path extending within a honeycomb body perpendicular to the common direction, at least a high aspect ratio portion of the first fluid path having an aspect ratio of height in the common direction to width perpendicular to the common direction and to the first path direction of at least 3:1, and a second fluid path extending perpendicular to the common direction, the second fluid also having a high aspect ratio portion having an aspect ratio of at least 3:1, wherein the first fluid path is fluidically connected to the second fluid path within their respective high aspect ratio portions via a group of apertures, the group extending in the common direction, the group of apertures taken together having a ratio of height to width of at least 3:1.

First claim

What is claimed is:

1. A honeycomb body interdigitating mixer, the body having parallel cells extending along a common direction, the mixer comprising:
a first fluid path extending within the honeycomb body along a first path direction perpendicular to the common direction, the first fluid path defined within a first plurality of said cells, at least a high aspect ratio portion of the first fluid path having an aspect ratio of height in the common direction to width perpendicular to the common direction and to the first path direction of at least 3:1; and
a second fluid path extending within the honeycomb body along a second path direction perpendicular to the common direction, the second fluid path defined within a second plurality of said cells, at least a high aspect ratio portion of the second fluid path having an aspect ratio of height in the common direction to width perpendicular to the common direction and to the second path direction of at least 3:1;
wherein the first fluid path is fluidically connected to the second fluid path within their respective high aspect ratio portions via a group of apertures, the group extending in the common direction, the group of apertures taken together having a ratio of height in the common direction to width perpendicular to the common direction of at least 3:1.

2. The mixer according to claim 1 , wherein a third plurality of said cells, including cells adjacent the first and second pluralities of cells, is open at both ends of the body or is otherwise provided with or enabled to receive a flow of thermal control fluid.

3. The mixer according to claim 1 , wherein the aspect ratio of the high aspect ratio portion of the first and second fluid paths is at least 5:1.

4. The mixer according to claim 1 , wherein the aspect ratio of the high aspect ratio portion of the first and second fluid paths is at least 9:1.

5. The mixer according to claim 1 , wherein the respective high aspect ratio portion of one or both of the first and second fluid paths includes the entire length of the respective fluid path, optionally excluding fluid ports for access to the respective paths from the exterior of the honeycomb body.

6. The mixer according to claim 1 , wherein the second fluidic path extends along its respective path direction on both sides of said group of apertures, and wherein the second fluid path includes a low aspect ratio portion along said path on at least one side of said group of apertures.

7. The mixer according to claim 1 , wherein the first fluid path ends at the group of apertures.
