Building fire simulation with a field model based on large eddy simulation

摘要

Building fire environment was simulated by afield model, or application of Computational Fluid Dynamics (CFD), based on large eddy simulation (LES). The Fire Dynamics Simulator (FDS) model based on LES, developed at the Building and Fire Research Laboratory, National Institute of Standards and Technology, USA, was applied to study the plume flow induced by a fire; and the fire environment in a compartment. Part of the results were compared with those predicted by another CFD package based on Reynolds averaging of the Navier-Stokes equations through the modified k-ε model.
