Abstract

The dynamic process of the interaction between a turbulent jet methane diffusion flame and a lateral wall was experimentally studied. The evolution of the flame temperature field with the Nitrogen dilution of the methane jet flame was studied for 0.2N2, 0.4N2, 0.6N2, 0.8N2, the interaction between the diffusion flame and the lateral wall is characterized for different distance between the wall and the central axis of the jet flame, the dilution is found to play the central role in the flame extinction process. The flame response as the lateral wall approaches from infinity and the increasing of the dilution rate make the flame extinction more rapidly than the flame without dilution, when the nitrogen dilution rate increase the flame temperature decrease.
