Abstract

Effects of different turbulence intensity on NO formation propagating planar premixed CH4/H2/air flame are investigated via direct numerical simulation. A detailed chemistry mechanism including 28 species and 268 steps is adopted. It is found that turbulent vortex would penetrate the flame front and sustain in the flame inner zone under the condition of high Karlovitz number. Local heat release rate increase to 1.8 times of that found in laminar flame, due to the strong stretch. The turbulent flame velocity based on the consumption rate increase significantly, however the total production rate of NO varies a little. Under intense turbulence, the total production rate of NO in the flame decrease, which is due to the significant decrease of the production rate of prompt NO.
