A Comparison Between Numerical Calculations and Experimental Measurements of the Structure of a Counterflow Methane-Air Diffusion Flame

Abstract

Results of a theoretical experimental study of the structure of a methane-air counterflow diffusion flame 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 including C2 chemistry were performed with an adaptive nonlinear boundary …
