Introduction Self-heating behaviour of dust accumulations is a multiphysics field coupled heat and mass transfer in the porous media. A typical experimental apparatus with a hot storage oven and mesh wire baskets has been taken as the study object. The influence of gas flow velocity, oxygen concentration and ambient temperature on the self-heating behaviour of the dry coal dust sample has been investigated with COMSOL Multiphysics® software.
