Abstract:

Polymer combustion is a highly complicated process where chemical reactions may occur not only in the gas phase, but also in the condensed phase as well as at the solid-gas interphase. The complication arises due to the coupling between the condensed phase and gas phase phenomena. While some polymers form a char layer during combustion, others exhibit swelling, bubbling, melting, sputtering, and multi-stage combustion. The combustion of polymeric materials is related to many applications including solid and hybrid rocket propulsion, and of recent interest, waste incineration.
