Abstract

A simple one-dimensional analytical model has been developed to describe the processes involved in the transient burning of non-charring thermoplastic materials. The model includes conduction, convection, and radiation effects for flaming materials. The burning rate solution is obtained by numerically solving an ordinary differential equation and an algebraic equation with flame radiative heat flux as a specified variable. The effect of convective blowing is also included in the model. The model is used to compute the flame heat fluxes for PMMA pool fires at various sizes. The results show the range of convective and radiative heat fluxes from the PMMA flame for pool fires ranging from 0.023 to 1.50 m² or 0.151 - 1.22 m diameter.
