“…It appears that geometrical considerations on the obstruction area are taken into account whereas no radiative properties of the vegetation surface itself are involved. In a recent contribution [2] a preliminary study has been presented on the radiative properties of six species of the Mediterranean region. It has been demonstrated that a correction can be introduced in order to take into account the actual non-black behavior of the plant matter in the infrared.…”

“…About the apparent flame temperature, it should be noted that it was computed according to Eq. 21 and that flame emissivity was obtained thanks to Beer's law [21], given by formula (22), after assuming an extinction coefficient of 0.72 m -1 experimentally determined for forest fuels by À gueda et al [22]. forward and backward fire fronts is illustrated in Fig.…”

The aim of this paper is to present some improvements in the metrology of forest fire flames by coupling image processing and radiative heat flux measurement. A new metrological tool using a visual video camera and a specific multiple thermal sensors is proposed. By means of an appropriate segmentation algorithm and the Direct Linear Transformation, the image processing methodology gives the forward or the backward fire front positions as input data to a radiative heat flux approach. Using a simplified flame model, this technique provides fire front positions versus time, and average values for the flame length, flame depth, flame tilt angle, apparent flame temperature and flame emissivity. The rates of spread, obtained by a linear regression of the determined fire front positions, as well as the thermal and radiative properties of the flame, are compared favorably to those given in the literature.

“…The wavelength dependence of pine needles was demonstrated by Monod et al [22]. However, Acem et al [23] showed that the absorptivity of a layer of dry needles was higher than the one of pine needles as a material and was close to 1 in average (see table 3).…”

Pine needle litters, a key fuel in coniferous forest systems, are highly porous fuel beds. They provide a source of continuous fuel medium that can be easily ignited and will sustain flame spread on the ground during forest fires. This work represents an experimental study that is focused on the influence of the fuel moisture content on the burning dynamics and the flammability characteristics of forest fuel beds. The FM Global Fire Propagation Apparatus was utilized to obtain time to ignition, heat release rate, total heat released and CO/CO 2 concentration data. The methodologies applied in previous studies were improved with new modifications. The results were analyzed with respect to the sample's fuel moisture content as well as other test conditions, such as airflow condition (wind), sample holder openness and external heat flux. The importance of the fuel moisture content is critical to understand as the majority of fuels present in the natural environment have elevated moisture content compared to dead dry fuel. Samples studied are representative of wet ground fuels as well as live fuels which do burn when crowning conditions develop. The results presented here are a building block for developing an experimental database that can be used to understand the influence of environmental conditions on the flammability of porous forest fuels and assess the risks that comes with a wildfire. Furthermore, the data can also be used for fire behavior model validation.
