A comparison between numerical calculations and experimental measurements of the structure of a counterflow diffusion flame burning diluted methane in diluted air

Results of a theoretical and experimental study of the structure of a counterflow diffusion flame burning diluted methane in diluted air are reported. Concentration profiles of the stable species were measured using gas sampling techniques with quartz microprobes. The samples were analyzed with a gas chromatograph. Temperature profiles were measured using coated thermocouples. Numerical calculations of the structure of the flame were performed …
