TL;DR: In this paper, an enhanced flame spread model is used to simulate a rail car fire and investigate the effects of configuration and burnable properties of interior m aterials on the fire development, and the results show that the model is better able to reproduce the fire experiment results compared with flame spread models using the ignition tempera ture as the sole ignition criterion.

Abstract: In this paper, an enhanced flame spread model imple mented in the SMARTFIRE CFD fire simulation software is used to simulate a rail car fire. The study focuses on three areas: demonstrati ng the shortcomings of the single criterion of surface ignition temperature in flame spread models; reproducing the rail car fire using the enhanced fl ame spread model and investigating the effects of configuration and burnable properties of interior m aterials on the fire development. The results show that the enhanced flame spread model is better able to reproduce the fire experiment results compared with flame spread models using the ignition tempera ture as the sole ignition criterion. The results a lso demonstrate that the configuration of the interior furniture and burnable properties of materials are important factors affecting the time to flashover.

Coupled Fire/Evacuation Analysis of the Station Nightclub Fire
TL;DR: In this article, coupled fire and evacuation simulation tools are used to simulate the Station Nightclub fire, which differs from the analysis conducted by NIST in three key areas; (1) an enhanced flame spread model and a toxicity generation model are used, (2) the evacuation is coupled to the fire simulation, and (3) it is suggested that both predictions of the flashover time are approximately 15 sec earlier than actually occurred.
