An Investigation of Methane-Air Nonpremixed Combustion in a Rapid-Mixing Burner

Abstract An experimental analysis was performed on a rapid-mixing burner in which the mixing of methane and air occurs in discrete vortex structures prior to burning. Air is distributed by large vortex structures, and burning of fuel-air are mixtures occurs in smaller eddies. The burner design was evaluated by utilizing various visualization and diagnostic techniques. The advantages and disadvantages of each are discussed. High speed video is …
