Comparative assessment of CFD Tools and the Eurocode Methodology in describing Externally Venting Flames

摘要: The ability of currently available Computational Fluid Dynamics (CFD) tools to adequately describe Externally Venting Flames (EVF) is assessed, aiming demonstrate compliance with performance-based fire safety regulations. Fire Simulator (FDS) CFD tool used simulate the EVF characteristics in a corridor-compartment-facade configuration exposed natural conditions. Numerical results temporal evolution gas velocity, temperatures and flame shape are obtained for both interior exterior compartment. Predictions compared respective experimental data, as well correlations suggested by Eurocode methodology. effects ventilation conditions investigated simulating Forced Draught (FD) No (NoFD) test cases. suggest that capable achieving good qualitative agreement data and, certain cases (e.g. FD conditions), adequate quantitative agreement, generally outperforms prescriptive
