Fire in confined spaces: reality and numerical simulations

Fire and smoke in enclosed spaces behave differently from those in open ones. Depending on scenario dimensions, fuel and ventilation, the fire passes through different stages after ignition. Together with the performance of real experiments, the use of Computational Fluid Dynamic models can be very useful to understand fire propagation behavior. In this work, we compare numerical results with real observations and measurements. The “Fire Dynamics Simulator” (FDS), based on Large Eddy Simulation techniques, is used to reproduce some real scenarios under the same fuel and ventilation conditions. Dynamical evolution of several magnitudes such as temperature, pressure, oxygen concentration and combustion products is evaluated and discussed.Peer Reviewe
