Abstract:

Flame spread over solid surface has been a research topic in combustion and fire science for more than thirty years. A spreading flame involves many interactive sub-processes: fluid flow, heat and mass transfer, solid thermal decomposition, gas-phase chemical kinetics and multi-dimensionality. To make a flame-spreading problem 'tractable' theoretically, a number of simplifying approximations are normally made. This often limits the usefulness of the model results. With the increase of computational capability, more detailed processes can be included. With impetus from the NASA's microgravity combustion program, considerable progress has been made in modeling small-scale laminar flame spread over solids over the past dozen years. In this talk, some of the advances made will be reviewed, the possible applications of current models will be discussed and future research that can extend the capability of the present day models will be mentioned.
