An experimental study is conducted on the emission of volatile organic compounds (VOCs) emitted by Rosmarinus officinalis plants when exposed to an external radiant flux. The thermal radiation heats plant and causes VOCs. simulates flux received vegetation in a forest fire. results experiments are used simplified analysis determine if emissions VOCs actual fire situation could produce flammable gas mixture potentially lead onset accelerating consist placing hermetic enclosure heating it with...
In situ Raman scattering studies allow following real‐time evolutions of volume or surface structures under extreme conditions. nuclear materials sciences, ion irradiation‐induced atomic organization modification and water radiolysis are a major interest. order to better understand these phenomena, we have developed an in versatile portable spectroscopy system coupled with cyclotron accelerator, allowing monitoring solid/liquid interface irradiation thus giving access effects radiolysis. The...
Forest fires are can be fatal for firefighters owing to the phenomenon of eruptive fire. The hypothesis this study is that biogenic volatile organic compounds (BVOCs) accumulate in vicinity fire front. One factors required an take place BVOC concentrations must between their lower flammable limit and upper limit. When accumulation BVOCs exacerbated by specific geographical zones (e.g. small valleys, thalwegs, canyons), combination these two lead situations with a very high flammability...
The aim of this article is twofold. First, it concerns the improvement knowledge on fundamental physical mechanisms that control propagation forest fires. To proceed, an experimental apparatus was designed to study, in laboratory conditions, flame a fire spreading across pine needle fuel bed. Characterization temperature managed by using reconstruction method based double thermocouple probe technique developed recently. vertical gas velocity distribution derived from previous reconstructed...
Prescribed fires can be used as a forest management tool to reduce the severity of wildfires. Thus, over prolonged and repeated periods, firefighters are exposed toxic air contaminants. This work consisted in collecting analysing smoke released by typical Mediterranean vegetation during prescribed burning. Sampling was performed at five active zones on island Corsica. Seventy‐nine compounds were identified: volatile organic semi‐volatile compounds, including polycyclic aromatic hydrocarbons....
Abstract Two samples of virgin olive oil and one sample hexane‐extracted husk coming from Iran were examined. The analyses included physical chemical characteristics, the composition total fatty acids at glyceride 2‐position by gas liquid chromatography (GLC) methyl esters, triglycerides calculation according to Vander Wal theory, separation alcoholic fractions (sterols, 4‐methylsterols, triterpene alcohols, dialcohols aliphatic alcohols) unsaponifiable matter thin layer (TLC), quantitation...
Peat is an organic and flammable material used for energy generation involved in accidental wildfires. Smoldering combustion governed by heterogeneous chemical reactions of drying pyrolysis the bulk solid oxidation at surface. In these phenomena, process its rate important mechanism. The aim this research was to determine thermokinetic constants (TKCs) different scales boreal peat samples from two regions three depths. experiments various kinds were mathematically described methods. To...
Fire behavior prediction models required for controlling wildland fires can be calculated from a mathematical approach, taking the thermal and chemical properties of forest fuels into account. There is need better understanding decomposition fuels. Two steps have been observed during degradation Pinus pinaster needles under air sweeping. The two corresponding exothermic peaks showed by DSC curves are superimposed. An original simple method proposed to separate each peak global exotherm then...
The analysis of combustion kinetics in the gas-phase is decisive for wild land fire behavior modeling. However, use detailed reaction mechanisms, which involves a large number species and reactions, impractical due to computational time requirements. present work proposes five-step chemical kinetic mechanism simulate gas phase processes taking place wildland fires. Both experimental data from simulations run using PSR code CHEMKIN-II package with (GDF-kin 3.0) have been used calibrate...
Climate change causes more frequent and destructive wildfires even transforming them into megafire. Moreover, all biomass fires produce emissions of carbon compounds in the form soot to atmosphere with a significant impact on environment human health. Indeed, is causing formation PAHs from (a) high temperature thermal alteration natural product precursors source organic matter (b) recombination molecular fragments smoke. However, these molecules are known have carcinogenic effects It...
Fire behaviour prediction models, required for controlling wild-land fires, can be calculated from a mathematical approach, taking the thermal and chemical properties of forest fuels into account. To improve extend applications ofthe model, we need better understanding different phenomena involved in decomposition fuels. Three steps have been observed during degradation Pinus pinaster needles: dehydration, oxidization evolved gases char combustion. Kinetic parameters first step were...
This work consists in sampling and analyzing volatiles smoke released by a typical Mediterranean vegetation during fire. On an experimental burning plot, we used two original devices to collect smoke. Thanks air pumps, atmosphere samples were taken, into cartridges filled with adsorbent tedlar bags. The test site was instrumented different other sensors (thermocouples, fluxmeters, anemometers, IR visible cameras) order get the maximum data [1]. Analyses performed at laboratory gas...
