Abstract

Abstract: This piece of work is a contribution to the model-building and numerical simulation of fire phenomenon concerning fire outbreak, in confined enclosures. The numerical tool that has been used is the industrial Computational Fluid Dynamics (CFD) code called Fire Dynamics Simulator (FDS), in its 5.5.3 version. The chosen configuration of Foote and Chen et al. has allowed us to evidence the ventilation phenomena. The results of calculations that we carried out under over-ventilation conditions were satisfactory. A gap is nevertheless observed between calculations and measurements when the measurement point is located close to the air inlet duct. In under-ventilated conditions, the results are equally satisfactory, but appear to require heat flow sensitivity analysis to be excellent.
