Abstract
Smoldering in porous media is a very complex situation that happens in situations where a reactive part of the porous material is oxidized using heat content without flaming. A three-dimensional numerical tool for the simulation of smoldering in fixed beds of solid fuels is presented in this paper. The description is based on the microscale equations, in a detailed discretized image of the porous medium. A set of 3D simulations demonstrates the ability of the model to handle a variety of situations, and to provide detailed local information. The cases treated here are clearly orientated to standard experimental cases.
Most computations were performed at CINES (Montpellier, France), subsidized by the MENESR, whose support is gratefully acknowledged.
