Abstract

A counterflow configuration is considered to study flame responses of laminar diffusion flames for general fluid mixtures over the entire thermodynamic regimes. Both subcritical and supercritical temperatures and pressures are included. A unified treatment of thermophysical properties based on fundamental thermodynamic theory and extended corresponding state principle is incorporated into the flame calculations in an opposed flow field. A two-point temperature-controlling continuation method is applied to treat the singularity problem at the turning points on the folded S-shaped curve. The resultant numerical scheme is capable of studying laminar counterflow flame structures over the entire S-curve at any fluid state with detailed chemical mechanism. Both oxygen/hydrogen and oxygen/methane flames are investigated over a broad range of pressures from 0.5 atm to 200 atm. The strain rate varies from a small value to the maximum value (up to 2.0×108 s-1) in extinction state. The effects of oxygen injection temperature on the flame structure are also discussed in detail.
