Investigation on the combustion performance enhancement of the premixed methane/air in a two-step micro combustor

After a two-step global reaction mechanism is used to compute the chemical reactions of the reacting flows, a premixed methane/air combustion model of a two-step micro combustor is established based on some effect factors such as step angle, wall materials and inlet velocity. Moreover, the three or four kinds of the micro two-step combustors are used to investigate the effect of flame shape in the micro-channel, temperature characteristic,...
