For recent researches, Cheney et al. 1-2 have ide

36、d rate of reaction for modelling the combustion processes. However, until now, fire management tools have been developed from empirical or statistical models only, and many existing physical models cannot be used as prediction tools since they consider the fire front as an infinite straight line. Th

37、us, these models can only give valid outputs for horizontal fire in still air because they are not able to provide the curvature of the up-wind or up-slope fire front shapes. Furthermore, few of them include both wind and slope effects.The aim of the present paper is to develop an accurate numerical

38、 model which is capable of describing the spread of a forest fire in order to help fire fighters facing a fire to make the appropriate decisions. This necessitates a simple model capable of predicting the key features of a fire and a numerical method of resolution for fire behavior simulation. In th
