Abstract

Experimental and numerical investigations were performed for the laminar burning velocity and the flame structure of laminar premixed CH 4/O2/CO2 flames. Measurements of the laminar burning velocity were conducted by using a flame cone angle method for a circular nozzle burner. Numerical simulation was performed using one-dimensional plane flame code including radiation heat loss with an optically thin model. It was shown that the laminar burning velocity decrease with CO2 addition even though the adiabatic flame temperature is the same as that for CH4/Air flames. The radiation heat loss is significant for the CH4/O2/CO2 flames, and the flame temperature and laminar burning velocity decreases when the radiation heat loss is considered. Effects of thermal properties, radiation, and chemical reaction on the determination of the laminar burning velocity of CH4/O 2/CO2 flames were discussed.
