title: Two-dimensional quantitative measurements of methyl radicals in methane/air flame.
abstract: Two-dimensional (2D) quantitative measurements of methyl (CH3) radicals in a methane/air Hencken flame at atmospheric pressure are performed using coherent microwave Rayleigh scattering (Radar) from Resonance Enhanced Multi-Photon Ionization (REMPI) technique. The 2D scanning and subsequent quantification are employed for Radar REMPI. The 2D quantitative results are used to verify the numerical calculations. The line-integral effect was involved in the calculation due to the real experimental configuration. A 25% difference existed between the experimental results and numerical calculation, while the overall concentration distributions between experiment and modeling of single flamelet have fairly good agreement with each other.
