Under strong wind conditions, many firebrands generated from a burning house will disperse to distant places, thereby engendering spreading damage by leaping flames. This may result in a large urban fire. Firebrands and leaping flames caused by them are important factors to clarify the mechanism of urban fires. Nevertheless, their systematic study has not been greatly implemented because of limited availability of experimental facilities. Therefore, the authors established a CFD simulation model of firebrands scattering, which includes experimental data on density and mass decrement of firebrands during scattering. And real urban fire was reenacted by this model to verify the simulation accuracy.
