RESUMO
A transient one dimensional model is applied to study degradation and combustion of a poly methyl methacrylate (PMMA) sample. Ignition of PMMA is a complex interaction among different mechanisms, including solid fuel degradation, heat transfer, in-depth absorption of radiation, surface regression and gas-phase advective heat/mass transfer and combustion. The present task has the significant feature of coupling the solid and gas phases. Besides the mathematical model has been solved numerically by using a fast iterative method and has yielded realistic results.
