Abstract

Externally Venting Flames (EVF) may significantly increase the risk of fire spreading. The main scope of this study is to investigate the fundamental physical phenomena governing EVF development and to assess the ability of currently available CFD tools to adequately describe EVF characteristics. In this context, a series of medium scale compartment-façade configuration fire experiments are performed. Experimental results suggest that the fuel load has a significant impact on the heat flux to the façade. The Fire Dynamics Simulator (FDS) CFD tool is used for the numerical simulation of the turbulent, multi-component and reactive flow-field developing in the experimental apparatus.
