Enhancing Combustion Analysis: Implementation and Validation of Laminar Premixed Methane-Air Jet-Impinging Flame Simulation in OpenFOAM

Abstract

This research utilized the open-source toolbox OpenFOAM to conduct a numerical investigation of the laminar premixed methane-air jet-impinging flame. OpenFOAM, a software based on computational fluid dynamics (CFD) and employing the finite volume method (FVM), was used to perform transient simulations with a chemically compressible reacting flow model integrated with a conjugated heat transfer model. Key parameters such as burner-to-plate distances (H/d = 0.04 and 0.06 m), mixture equivalence ratios (ɸ = 0.8-2.0), and Reynolds numbers (Re = 500, 750 and 1,000) were varied to thoroughly examine their effects. The simulated results were rigorously validated against experimental data from previous research, focusing on flame height and thermal efficiency, which are critical parameters in the jet-flame impinging system. The validation demonstrated a strong correlation, confirming the accuracy and reliability of the simulations. This alignment underscores the usefulness of          the modeling approach and highlights the potential of using OpenFOAM for detailed combustion studies, paving the way for future research and optimization in this field.
