Chemical effects of CO2 dilution on CH4 and H2 spherical flame

CO2 dilution is an effective strategy for combustion control. To understand the detailed dilution effects of CO2 (including physical effects and chemical effects) on CH4 and H2 combustion, an open-source CFD package laminarSMOKE was utilized to simulate the transient one-dimensional outwardly spherical flame combustion process in a closed chamber under 0–15% CO2 dilution mole fraction (α), at 293 K, 1 bar, stoichiometric ratio. The overall CO2...
