Comparative Analysis of CFD Modeling Methane Combustion in a Jet Using Various Turbulence Models

The article investigates the modeling of the turbulent diffusion combustion process of a methane–air jet using the COMSOL Multiphysics software package. This software is highly effective for simulating coupled phenomena involving the interaction of multiple physical processes, such as combustion. To model turbulent diffusion combustion, the interactions between turbulent flow, species mixing, chemical reactions, and heat transfer in fluids were taken into account. The k–ω, k–ε, and k–ω (SST) turbulence models were employed to simulate fluid flow, while the eddy dissipation model (EDM) was used to describe the combustion process. Methane combustion was represented by a two-step reaction mechanism involving the intermediate formation of carbon monoxide. The obtained temperature distribution results were compared with available experimental data.
