Description: A three dimensional differential field model for the spread of fire and smoke, on general      orthogonal coordinate systems is developed. The model, which is designed for closed spaces,      also includes the physical effects of turbulence, strong buoyancy, full compressibility, pressure      rise due to fire loading, surface-surface and surface-flame radiation exchange, and heat losses      through the wall. It is based on a control-volume staggered-cell finite- difference approach      with primitive variables. Results of numerical calculations based on the field model are      compared with test data for a methanol fire in the NRL FIRE I test facility which is in the form      of a closed pressure vessel. Reasonable comparisons of the resulting pressure and      temperatures at several locations have been obtained. Also shown are the detailed velocity      and temperature fields inside the vessel at different time instants after the commencement of      the fire. (mjm)
