 “CH₄/Air premixed flame attached to a carbon-coated brass matrix cooled with water. Fuel rich to fuel lean from left to right and top to bottom by increasing air flow rate and decreasing CH₄ flow rate. Small flames dance around and a butterfly appears. When the butterfly flies away, flame is gone.”
