Abstract:

The complex chemistry of a methane-air flame doped with phosphorus-containing compounds (PCCs) was determined and it was validated with experimental data. Modeling of partially stirred reactors (PaSR) by stochastic Monte Carlo simulations was carried out to investigate flame inhibition by PCCs considering the effects of turbulent mixing. Effects on flame structures were determined by varying the ratio τmix/τres (the residence time τres and the mixing time τmix). Numerical simulations were performed for a wide range of τmix and τres revealing extinction behaviors. A detailed investigation of catalytic cycles involved in the recombination of key flame radicals is discussed.
