Abstract

A successful simulation of compartment fires using computational fluid dynamics (CFD) must be able to adequately model three significant phenomena: the combustion of fuel, the mixing caused by the buoyancy of hot gasses, and the removal of heat from the gas phase by radiative transport. Unfortunately, these phenomena span a tremendous range of length and time scales. Combustion occurs at tiny length scales, whereas the mixing and radiative transport occur at the compartment length scale. In practical terms radiation heat transfer is instantaneous whereas the combustion process and the hydrodynamic transport of mass and energy is not. Given the current state of technology it is impractical to perform a meaningful calculation at the smallest required length and time scales.
