Heat transfer between hot combustion gases and a cold wall in narrow channels for limit flames
Abstract
Jarosinski (1983) presented measurements of the length of the hot region behind the flame front of methane-air mixtures in a narrow channel for limit flames. In the present study, results of these measurements are used to determine the real values of the heat transfer parameters. The aim of the measurements was to determine the flame structure in narrow channels under conditions approaching those of quenching. Results are given in the form of the dimensionless length of the hot region near the quenching limit in a narrow channel; and the Nusselt number as a function of quenching distance and equivalence ratio under limit conditions.
