Abstract

A numerical study on premixed combustion of CH4 + CO2 + Air in two dimensional is done. Parameters of inlet velocity and temperature of fuel and combustor geometry and size are considers the same but the CO2 dilution rate changes. Results of this simulation shows that while the CO2 dilution rate increases, flame temperature and velocity decrease. There is a limitation for increasing of CO2 in the mixture. If amount of CO2 in the mixture goes beyond the 47.7%, the fuel will lose its ability to be ignited and thus there will be no flame in the combustor. In addition, knowing the maximum temperature of flame may help to analyze the combustion process and choose suitable material in manufacturing the micro combustor.
