Abstract:

Fire propagation is driven by the coupling of heat and mass transfer processes between the gaseous and the condensed phases. A significant portion of the heat transfer rate is provided by radiative heat transfer mechanisms of which soot radiation contributes significantly for many flames. Although time history effects are suspected to affect the dynamics of soot evolution within heavily sooting non-premixed flames, the majority of soot chemistry calculations have been conducted for steady flame configurations.
