چکیده انگلیسی
The determination of the characteristics of the flame and of the upward gas flow velocity in the flames is very useful for combustion and forest fire modelling. In this paper, we intend to show that this velocity can be measured by a specific thermal sensor using a flame model. Two flame models have been considered but the fire front has been considered as a plane moving at a constant rate of spread and characterised by some geometric and physical parameters. These characteristics of the flame have been identified from experiments with the inverse method. Very similar values were obtained by the two models. The upward gas flow velocity has also been deduced using a least-squares regression based on the values of the parameters of the flame.
