The structure of nonpremixed methyl chloride and methyl chloride/methane air flames near extinction

Experimental measurements are conducted to determine the structure of counterflow halogenated flames near extinction. The flames are simulated using a detailed chemical kinetic mechanism. Two flames are studied, one burning methyl chloride, and the other an equimolar mixture of methane and methyl chloride as fuel. The measured velocity, temperature, and species composition profiles are compared with the calculations. Whereas there is overall good agreement between the measurements and predictions, it appears that methyl chloride consumption occurs at a rate slower than predicted, and some areas of further refinement in the kinetic mechanism are identified.
