Parametric CFD analysis of the setting data on evaluation of the Safe Egress conditions in case of fire using FDS

The CFD simulation allows to simulate fire scenario to evaluate parameters influencing Safe Egress. The essential prerequisites to CFD simulations to assure realistic fire conditions of high quality and reliability are the knowledge of fire parameters, such as ignition time and Heat Release Rate of the items involved in the combustion process. Sometimes, the thermo dynamical parameters such as density, thermal conductivity, thermal capacity are not well known or although experimentally measured they are affected by an uncertainty interval; this means that there is a range of values which can influence, significantly, the ignition time and HRR of the combustible materials. The main aim of the present work is to evaluate, by means CFD case study, the influence of uncertainties of input data on the evaluation of environmental conditions for the public building Safe Egress.
