Recursive flow gas mixer

A gas mixing system, comprising:

• a gas mixer including:
• a tubular body having a wall extending longitudinally from a first end to a second end and having an outer side and an inner side, the inner side surrounding a central through opening and defining a first flow path between the first end and the second end;
• one or more inlet holes formed in the outer side of the wall;
• a plurality of exit holes formed in the inner side of the wall and communicating with the central through opening;
• and
• a plurality of longitudinal channels formed within the wall fluidly coupled to the one or more inlet holes and the plurality of exit holes, wherein the one or more inlet holes, the plurality of exit holes, and the plurality of longitudinal channels define a recursive second flow path that intersects with the first flow path in the central through opening;
• a first annular channel formed within the wall coupled to the one or more inlet holes;
• and
• a second annular channel formed within the wall coupled to the plurality of exit holes,
• wherein the plurality of longitudinal channels extend between the first annular channel and the second annular channel;
• a first gas supply coupled to the central through opening at the first end;
• and
• a second gas supply coupled to the one or more inlet holes.

A method of gas mixing, comprising:

• introducing a first gas through a central through opening of a tubular body having a wall extending longitudinally from a first end to a second end and having an outer side and an inner side, the inner side surrounding the central through opening;
• introducing a second gas through one or more inlet holes formed in the outer side of the wall, wherein the introduced second gas flows through a plurality of longitudinal channels formed within the wall to a plurality of exit holes formed in the inner side of the wall and exits the plurality of exit holes into the central through opening and mixes with the first gas;
• and
• transporting the mixed first and second gases through the central through opening to the second end,
• wherein the introduced second gas enters a first annular channel formed within the wall before entering the plurality of longitudinal channels and enters a second annular channel formed within the wall before exiting the plurality of exit holes.
