Abstract

This report compares results of simulations performed using the NIST Fire Dynamics Simulator (FDS) with published experimental data, covering a wide range of conditions that are encountered in buildings. Whenever possible, these results have also been qualitatively compared with published simulations from other CFD programs. The issues of computing time and model assembly have also beeninvestigated in detail. The overall focus is to simultaneously consider both experimental verification and computing time, allowing users to build improved models and develop realistic expectations regarding speed and accuracy.
