Modeling wildland fire propagation using a semi-physical network model

(in lingua inglese)
A fast and simple surface fire model is presented, which combines the features of a network model with those of a semiphysical model of the interaction between the fire and vegetative cells which strongly depends on weather conditions, land topography, and vegetation. Radiation and convection from the flaming zone and embers, and radiative heat loss to the ambient are considered in the preheating process of unburned cells. The predictive capability of the model is partially assessed by comparison with data from laboratory-scale and prescribed burning experiments. Discrepancies between model results and measurements are observed. A better agreement should be obtained by increasing the accuracy with which model parameters are determined.
