“…Indeed, the flame heat flux increases through the reradiation of energy from the soot particles back to the burning sample. It is also interesting to observe that the heat fluxes evaluated here are comparable to those reported for the steady burning of vertical slabs of translucent PMMA. Indeed, depending on the sample height, the total flame heat flux varies approximately in the range 23 to 31 kW/m 2 with surface reradiation equal to 11.5 kW/m 2 .…”

“…Although the spectral distribution of radiation falling on the samples may affect the radiative properties due to the non-grey spectral nature of the polymers [34][35][36], spectrally averaged values are used in this study over the entire spectrum regardless of incident angle for simplification as those of Ref. [22,24,25,37].…”

“…The influence of the front interface decay on combustion in the gas region is not considered. However, since the distance from the front surface to the rear surface can be calculated, the time reaching the rear surface can be calculated and the change of the cell volume size ΔV solid for each solid cell is computed following Pizzo et al [8]:…”

“…More recently, Leventon and Stoliarov [7] measured the heat flux on the surface of a relatively small PMMA sample during upward flame spread. Pizzo et al [8] experimentally investigated transient pyrolysis of thick clear PMMA slabs exposed to radiant heat fluxes of 14 and 18 kW/m 2 . They also conducted a second series of experiments in which the PMMA samples were exposed to incident flame heat flux of 24.5 kW/m 2 .…”
