Research overview:
The purpose of this study is to develop a real time prediction method for a large-scale urban fire spread. Such large-scale urban fire is well known as the secondary disaster which follows a devastating earthquake. The real time prediction of fire can help smooth evacuation of residents from dangerous parts of a disaster area. In this study, CFD method is applied to simulate fire plume and its surrounding wind field. Spread of urban fire is mainly caused by strong heat radiation emitted from fire flame and by fire brands discharged from fire plume. With the results of wind field simulation, it is possible to simulate the fire brands and the radiation of fire flame which is inclined by the wind based on the coupling simulation. With all of these simulations, it will be possible to predict the fire spreading with enough accuracy and generality for any conditions.
