Abstract:

The evolution of the temperature profile within a solid capable of exothermic decomposition is derived from an approximate analytic solution of the equation describing heat conduction in the presence of continuously distributed heat sources due to chemical decomposition and to the absorption of an intense, short duration pulse of light. The critical light intensity capable of giving rise to a thermal explosion is deduced and a minimum critical intensity is shown to exist. The model predicts all the major experimental features of ignition by light.
