| 摘要 | The effects of the scalar dissipation rate (SDR) on the quenching points of the steady laminar flamelet model at different stoichiometric ratios of reactants are investigated for a one-step reversible reaction with the Arrhenius rate. SDRs are either presumed uniform or modeled by the mapping closure approach. With these two models, steady flamelet equations are solved in mixture-fraction space, and complete 'S-shaped' curves are obtained. The results show that the SDR models affect the locus of the 'S-shaped' curves and the quenching points are remarkably different. The quenching state is reached at a lower chi(st) for chi = chi(st) but at a higher chi(st) for chi = chi(st)exp[ -2 erfc(-1) (2z)(2)]. However, when the flame state is far from the quenching point, the difference in 'S-shaped' curves is small. This result is associated with the mixed state of the reactants; the poorer the mixing, the more remarkable the difference in 'S-shaped' curves becomes. |
