IMPACT OF SELECTED FIRE-MODELLING INPUT PARAMETERS ON THE SAFE AVAILABLE EVACUATION TIME

This article deals with the selected parameters affecting results of CFD computer fire models, namely the Fire Dynamics Simulator. The motivation for this analysis comes from the increasing use of the computer fire models and associated potential for error due to not-so-obvious importance of many input parameters. This paper is focused on the grid resolution, compartment geometry and fire specification in relation to the available safe evacuation time. It has been found that it is not possible to predict the effect of these parameters accurately by estimation only. This may affect design assumptions, e.g. increasing the area of smoke reservoir may not sufficiently increase the available safe evacuation time. It is therefore necessary to conduct a sensitivity analysis to establish the importance of all relevant input parameters.
