Toward pore-scale simulation of combustion in porous media using a low-Mach hybrid lattice Boltzmann/finite-difference solver

A hybrid numerical model previously developed for combustion simulations is extended in this article to describe flame propagation and stabilization porous media. The model, with a special focus on flame/wall interaction processes, validated via corresponding benchmarks involving channels both adiabatic constant-temperature walls. Simulations different channel widths show that the can correctly capture changes shape speed as well dead zone quenching limit, found cold further assessed considering pseudo two-dimensional burner an array of cylindrical obstacles at constant temperature, investigated companion experimental study. Furthermore, used simulate pore-scale dynamics randomly generated three-dimensional Results are promising, opening door future realistic
