The Effects of CO₂ Additional on Flame Characteristics in the CH₄/N₂/O₂ Counterflow Diffusion Flame

Molecules, 2021
The effects (chemical, thermal, transport, and radiative) of CO2 added to the fuel side and oxidizer side on the flame temperature and the position of the flame front in a one-dimensional laminar counterflow diffusion flame of methane/N2/O2 were studied.
