Abstract
The effect of a piecewise non-equilibrium gliding arc plasma discharge on the stabilization and extinction of nitrogen diluted, methane/air counterflow non-premixed flames was investigated both experimentally and numerically. Up to a 220 percent increase in the extinction strain rate was observed. To quantify whether the enhancement was from thermal or nonthermal effects, Rayleigh scattering thermometry and OH Planar Laser Induced Fluorescence (PLIF) was performed to obtain experimental temperature profiles. Numerical computation using detailed chemistry was performed to obtain temperature profiles with elevated temperature and radical addition as prescribed boundary conditions. The computation with only an increase in temperature to mimic the plasma agreed well with the experimental results. This suggested that the effect of a non-equilibrium plasma discharge with low gas temperatures on a non-premixed flame was dominated by thermal effects.
