Abstract :
[en] Fires in large compartments tend to burn locally and to move across the floor over a period of time, this particular behaviour has been discovered to challenge the assumption of uniform gas temperature in the fire compartment. Recent studies on fires in large compartments led to the now widely known concept of “travelling fires”. Several models have been proposed so far to describe the evolution in time of travelling fires. Although these models represented an innovative step in the field of travelling fire, major drawbacks of these models can be found in the simplification of fire dynamics (constant spread rate, 1D imposed fire path) and limited field of application (rectangular based geometries). The purpose of this paper is to present a numerical model of travelling fire. The model is based on an improved zone model combined with a cellular automata model. The software GoZone in which the model has been implemented is intended to be a practical solution to analyse fires in large compartments of potentially any shape. GoZone, is aimed to describe the complex dynamics of the fire, from ignition, to a phase of growing localised fire that may eventual travel in the compartment, possibly followed by a flashover. The main sub models composing GoZone are presented. A comparison is given with the results of under ventilated fire test 2 of the BST/FSR 1993 test series and with respect to the Veselì travelling fire test is shown. GoZone shows a promising capacity to represent fires in large compartment in both air and fuel controlled fire conditions.
