N2 - Downward flame spread over PMMA surface has been studied numerically by coupled heat and mass transfer model including two-dimensional elliptical equations both in the gas phase and solid fuel. Unlike the generally accepted approach based on the one-step macro-reaction for combustion, present model employs the two-step reactions mechanism in the gas phase. Solid fuel pyrolysis generates a gaseous product at the burning surface and, at the first reaction step, this relatively higher hydrocarbon decays into the lower-weight gas, which, in turn, reacts with surrounding oxidizer at the second reaction step, which is the combustion itself. The results showed that profiles of gas-phase temperature obtained through the two-step reaction model fit experimental data noticeably better than customary one-step reaction.
