The influence of fire ventilation on flame radiation is important in compartment fires especially for under-ventilated combustions. An approximate model for predicting flame radiant power and mean flame radiative temperature for both well and under-ventilated polymer fires is proposed on the basis of ?-correlations, in which the role of flame sootiness as well as the effect of fire ventilation is considered. The results were calculated for several typical polymers, and the effects of fire ventilation, chemical composition and structure of fuels, soot particle concentration and fire size were also investigated. The comparison with experimental data and the prediction from the Global Flame Radiation Model of de Ris and Orloff has been found to be satisfactory. This study attempts to provide: (1) a deeper scientific understanding of the effect of fire ventilation on flame radiation, and (2) available correlations, for the analysis of compartment fires.
