Understanding the phenomena of fire in enclosed spaces, such as those found on surface ships and submarines, will greatly enhance the Navy's ability to combat or prevent them. This computer model was developed for use in conjunction with Fire-1, and experimental fire chamber test facility at the Naval Research Laboratory in Washington, D.C. It is a three dimensional finite difference model which includes the phenomena of conduction, turbulence, global pressure correction, surface radiation and strong buoyancy flows. Given specific data on heat release, it predicts velocities, temperatures, pressures, densities and viscosities throughout its geometry. It has been reasonably validated by comparison with experiments in Fire-1. Advanced graphics techniques, such as color contouring and three-dimensional vector field plotting, have been applied to make output data more informative. This model, if easily modified to more specific geometries, may become a useful tool for naval architects in the design of the fire safe ship. 收起
