The purpose of this paper is to empower the scientific and technological
community with the knowledge to identify and define key concepts of fire modeling
and to develop the ability to apply the CFD (Computer Fluid Dynamics) tools to fire
investigation and prevention using basic mathematical models. Combustion, thermal
radiation, turbulence, fluid dynamics, and other physical and chemical processes all
contribute to the complexity of fire processes. Flame shape, plume behavior,
combustion product diffusion, and thermal radiation effects on neighboring objects can
all be modeled with Large Eddy Simulation (LES) software. This paper uses many
small and large-scale case studies under various boundary conditions to demonstrate
the strength of the Fire Dynamics Simulator (FDS), an LES code established by the
National Institute of Standards and Technology (NIST).
