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.
