Abstract

An approach to field modeling of fire phenomena in enclosures is presented. The conservation equations of mass, momentum and energy are calculated with sufficient temporal and spatial resolution to yield a truly three-dimensional, dynamic picture of the fire plume and its surroundings. The large-scale eddies are simulated directly and sub-grid scale motion is represented by a constant eddy viscosity. Efficient flow solving techniques make it possible to simulate fire scenarios using computational grids in excess of a million cells on modern workstations. Several examples of the methodology are presented.
