Laminar burning velocities of CH4/O2/N2 and oxygen-enriched CH4/O2/CO2 flames at elevated pressures measured using the heat flux method

Laminar burning velocities (SL) of CH4/O2/N2 and oxygen-enriched CH4/O2/CO2 flames were measured at elevated pressures up to 0.5 MPa and equivalence ratios ranging from 0.6 to 1.6. The oxygen molar fraction was varied from 0.18 to 0.23 in the O2/N2 mixtures and from 0.31 to 0.42 in the O2/CO2 mixtures. The experimental results showed good agreement with the results reported in previous works, validating the suitability and reliability of the...
