Heat Transfer in an Intumescent Material Using a Three-Dimensional Lagrangian Model

Abstract

The addition of heat transfer calculations to a three-dimensional, time-dependent numerical model of intumescent materials is described. Intumescent materials protect an underlying substrate from fire through endothermic chemical reactions producing bubbles and through the reduced thermal conductivity of the final porous char. These mechanisms are demonstrated for a single bubble and multiple bubbles. Both flow and temperature fields within the intumescent melt are determined by summing fields due to the individual bubbles.
