Description:
This workshop will focus on three broad topics, ignition and flame spread over solid materials, fire plume dynamics, and
enclosure fires. The mathematical modeling issues associated with these three topics form the basis for theoretical and
computational approaches to most fire scenarios. The thermal degradation of solid materials under convective and radiative
loading, the propagation of flame and pyrolysis fronts, and the production of gaseous fuel and combustion products form the
basis of the first topic. Particular emphasis will be placed on the use of mathematical models of these processes to interpret
standard ignition and flammability tests. The experimental database underlying the current understanding of fire plume dynamics
will be summarized. Models of fire plumes based on simple integral models coupled to data correlations, and more
sophisticated treatments based on computational fluid dynamics will be presented. The role of turbulence modeling and its
relation to the computational techniques employed will be explored. Enclosure fire models based on lumped parameter
descriptions ("zone models") will be described. The application of both large eddy simulation techniques and k-e turbulence
modeling approaches to interior fires in interiors with complex geometries will be discussed.
