MATHEMATICAL MODELING OF THERMAL-ASSISTANCE\N PHASE TRANSFORMATIONS OF COMPOSITE MATERIALS AT HIGH TEMPERATURES
Heat and mass transfer in composite materials (CM) at high temperatures (> 600 K) is simulated in the conditions of phase transformations of KM binders ™ith the formation of a porous coke residue and pyrolysis gases filtered through a porous residue. A mathematical 235 model and a method of analytical solution for determining the temperature field in both phases, separated by a mobile boundary of phase transformations, are developed. To determine the coordinates and velocity of the moving boundary, a transcendental equation is derived on the basis of analytical solutions of the heat conduction problems in both phases. The results of the analytical solution are obtained and analyzed.
