Abstract
The effect of a stabilized non-equilibrium gliding arc plasma discharge on the stabilization and extinction of nitrogen diluted, methane/air counterflow diffusion flames was investigated both experimentally and numerically. To quantify the effect, extinction limits and flame temperature profiles via Rayleigh scattering were measured, calculated and compared to numerical simulations using detailed chemistry. The results show that the extinction limits were significantly extended, with up to a 220 percent increase in the extinction strain rate with low levels of plasma power addition. Comparison between experimental and numerical simulations showed good agreement for low power plasma activation of the air stream, indicating that the combustion enhancement of the diffusion flame was dominated by thermal effects.
