Résumé
Abstract

Notre but à long terme est de proposer un simulateur de feux de forêt. Pour ce faire, nous avons développé un modèle phénoménologique de propagation. Nous l'avons ensuite fait évoluer afin de prendre en compte les transferts convectifs grâce à un écoulement simplifié. Dans ce travail, nous présentons de manière synthétique notre approche qui peut s'étendre à d'autres modèles phénoménologiques. Nous comparons enfin les prévisions du modèle à des expériences de laboratoire.

Our long-range aim is to propose a forest fire simulator. To this end, we have developed a phenomenological model of fire spread. Then, we have improved it in order to take into account advective transfers thanks to a simplified flow. In this paper, we present in a synthetic way our modelling approach that can also be applied to other phenomenological models. Finally, we compare the model predictions to laboratory experiments.
