Pressurized turbulent premixed CH4/H2/air flame validation using OpenFOAM

In this study, we use the Algebraic Flame Surface Wrinkling (AFSW) model to conduct numerical simulations of PSI (Paul Scherrer Institute) high pressure, turbulent premixed Bunsen flame experiments. The AFSW was implemented in open-source computational fluid dynamics solver OpenFOAM, and were performed using a two-dimensional axial-symmetric with standard k–ɛ turbulence wall functions. for two different fuel/air mixtures, namely, 100% CH4 volumetric ratio 60% + 40% H2 ratio. thermophysical transport properties mixture calculated as function temperature library Cantera (an suite tools problems involving chemical kinetics, thermodynamics, processes), together GRI-Mech 3.0 mechanism. It found that outcome OpenFOAM good agreement experimental results, quantitatively qualitatively. Further assessment results showed that, much chemistry, boundary/initial conditions significantly impact shape height.
