Fire behaviour studies of combustible wall linings applying fire dynamics simulator

Abstract

In this paper the results of a large eddy simulation of an ISO 9705 room corner fire are presented. The field model, Fire Dynamics Simulator (FDS) was used to study the corner fire with and without combustible wall linings. Comparison of the results from simulations with prescribed heating and published experiments showed that with 50 mm grid spacing it is possible to quite accurately reproduce the experimental temperature data locations inside the room. When a combustible wall lining is included a T-shaped flame pattern similar to that observed in the experimental study was obtained but only with a particular grid size and reaction model. Inconsistent results were obtained with varying grid sizes and reaction models when combustible wall lining tests were modelled
