Modeling of methane-air flames

The article is devoted to the development and testing of a mathematical model of methane-air flame combustion. Comparison of the calculation results with experimental data showed that the use of EDC and PDF combustion models with flamelets using detailed kinetic mechanisms in combination with eddy-resolving turbulence models provides the best results for all flames. However, such modeling requires significant computational resources. In some cases, simpler combustion models in combination with RANS/URANS turbulence models are sufficient to obtain acceptable results. To obtain correct modeling results when performing industrial cfd calculations, a preliminary analysis of the possibility of correctly using RANS turbulence models and simple kinetic mechanisms is necessary
