Numerical Investigation of Turbulent Premixed Combustion of Methane / Air in Low Swirl Burner under Elevated Pressures and Temperatures

Abstract

Turbulent combustion modeling of lean premixed methane/air gas mixture in a low swirl burner is carried out using Large Eddy Simulation (LES). The operating conditions of the experiment as well as simulation are carried out at elevated pressure and temperature. The first case-simulation is a premixed combustion model based on C-equation formulation, the second one is based on species transport – Eddy Dissipation Concept (EDC) model. Numerical results for axial velocity and turbulence intensity along the centerline showed a good agreement against the experimental data. Quantitative results of OH mass fraction contour showing the flame structure are in a plausible agreement compared to the experimental measurement.

Performance Analysis of Novel Perforated LPG Burner for Domestic Application

“…In addition, better way of combustion, and enhance thermal efficiency by utilizing a porous media as a premixed and preheated fuel-air mixture in a burner [22][23][24]. Ali et al [25] simulated a combustion in a low swirl domestic burner with lean premixed methane/air gas mixture.…”
