MODELING OF THERMOPHYSICAL PROCESSES IN THE IGNITION OF A SMALL WOODEN PLANK

A formulation and a numerical solution based on a mathematical model of a porous reactive medium are given to the problem of ignition of a wooden plank by the action of a fi re source. It is found that the ignition of the original reactant is determined by the processes of heat and mass exchange with the fi re source, drying, and pyrolysis (decomposition and synthesis reactions) of a dry plank, by the reaction of oxidation of carbon dioxide, and also by the thermophysical properties of wood.
