In this paper a numerical algorithm for the numerical modeling of multidimensional laminar flames with detailed kinetic mechanisms is described. The proposed approach is based on the operator-splitting technique, in order to exploit the best numerical method available for the treatment of reacting, stiff processes and transport, non-stiff processes. The algorithm was implemented in the OpenFOAM® framework and was validated for a laminar coflow flame fed with ethylene. The numerical simulations (performed with a detailed kinetic mechanism with ~170 species and ~4800 reactions) showed a satisfactory agreement with the experimental data (temperature and composition along the centerline), demonstrating the feasibility of the suggested methodology.

Abstract

In this paper a numerical algorithm for the numerical modeling of multidimensional laminar flames with detailed kinetic mechanisms is described. The proposed approach is based on the operator-splitting technique, in order to exploit the best numerical method available for the treatment of reacting, stiff processes and transport, non-stiff processes. The algorithm was implemented in the OpenFOAM® framework and was validated for a laminar coflow flame fed with ethylene. The numerical simulations (performed with a detailed kinetic mechanism with ~170 species and ~4800 reactions) showed a satisfactory agreement with the experimental data (temperature and composition along the centerline), demonstrating the feasibility of the suggested methodology.
