摘要：

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. (C) 1998 Published by Elsevier Science Ltd. All rights reserved.
