The dynamic process of the interaction between a turbulent jet diffusion
methane 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 examined. The interaction between the diffusion flame and
the lateral wall was investigated for different distance between the wall
and the central axes 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 rapid than the flame without dilution,
when the nitrogen dilution rate increase the flame temperature decrease.
