CFD-Based Modeling of Combustion and Suppression in Compartment Fires

Abstract

This chapter is aimed at illustrating contemporary Computational Fluid Dynamics (CFD) capabilities for compartment fire applications. We choose to use the Fire Dynamics Simulator (FDS) for illustration purposes. FDS is developed by the National Institute of Standards and Technology, USA, and is one of the leading fire simulation software available to fire protection engineers and scientists; it is both representative of current capabilities as well as indicative of future trends. The material in this Chapter is organized around a presentation of the different stages of a typical enclosure fire, from localized ignition to its fully-developed state. We present FDS simulations of model problems that serve to illustrate the performance and limitations of CFD-based descriptions for: (1) transient ignition phenomena and early fire growth; (2) smoke filling and pre-flashover fire spread; (3) possible flashover and transition to under-ventilated combustion; (4) activation of water-based fire suppression systems and subsequent fire control and/or extinction.
