Effects of CH−NO Interactions on Kinetics of Prompt NO in High-Pressure Counterflow Flames

摘要: Laser-induced fluorescence (LIF) measurements of nitric oxide (NO) and methylidyne (CH), previously reported for prompt-dominated laminar, counterflow, methane−air non-premixed flames at a global strain rate 20 s−1 pressures from 1 to 6 atm, are analyzed by considering three important aspects complex CH−NO kinetics. First, net reaction rates studied as function pressure so understand the observed peaks in maximum [CH] [NO] between 2 4 atm. Second, key elementary reactions compared two detailed chemical kinetic mechanisms, GRI 3.0 Lindstedt, order investigate differences computed [NO]. Third, variations coefficients those involving CH that strongly influence NO concentrations these flames. Rate also considered steps which directly affect formation destruction NO. On basis all inquiries, controlling ...
