Numerical simulations of freely propagating premixed flames burning mixtures of methane as fuel and trifluoromethane as an inhibitor were performed at atmospheric pressure in order to investigate the influence of trifluoromethane on CH₄/O₂/N₂ flames under the condition of the oxygen-enrichment. The calculated flame speeds were compared with those obtained from the experiments for flames at the oxygen-enrichment of 0.21, the results of which were in excellent agreement. Trifluouromethane significantly contributed toward the reduction of flame speed, the magnitude of which was larger by the physical effect than by the chemical effect. More trifluoromethane could be added and consumed on oxygen-enriched CH₄/O₂/N₂ flames. CHF₃ was decomposed primarily via CF₃→CF₂→CF→CF:O→CO and CHF₃+M →CF₂+HF+M had an important role in oxygen-enhanced flames. As an inhibitor was added on oxygen-enriched flames, the position of the maximum concentration of active radicals was shifted to the relatively low temperature range and the net rate of OH became higher than that of H.
