Jamaladdeen, Rawaa. "Investigation on Wildfire Flashovers in the Mediterranean Climate Regions with Emphasis on VOCs Contributions". Electronic Thesis or Diss., Chasseneuil-du-Poitou, Ecole nationale supérieure de mécanique et d'aérotechnique, 2023. http://www.theses.fr/2023ESMA0015.
Texto completoRequests from the firefighting communities are increasing urging the scientific communities to create operational protective and preventive tools that help them understand extreme wildfire behaviors considering not only the atmospheric conditions but also topography, and vegetation characteristics. Thus, our objective was to provide answers to such requests by investigating the probable factors responsible for intensifying wildfire regimes to flashovers using numerical, and thermobiochemical experimental approaches. The numerical model is a gas dispersion model validating experimental data from wind tunnel tests to resolve the controversy of whether or not the volatile organic compounds (VOCs) accumulations in confined topographies end up inducing wildfire flashovers. It comprises a propagating fire front calculated using the Rothermel semi-empirical steady-state surface fire model, and Van Wagner transition to crown fire behavior criteria, with an integrated unsteady rate of VOC emissions simulating the ones evolving from the vegetation burning in the firefront. To synchronize our work with field input, thermochemical experiments were conducted on various Mediterranean vegetation species to examine their VOC emission rates in normal and stressful environmental conditions as they may end up defining different flammability scenarios in wildfires. First, two Mediterranean shrub species: Cistus albidus and Rosmarinus officinalis are explored for their VOC emissions and physiological changes after being subjected to abiotic stresses (drought and heat), using pyrolysis-gas chromatography and mass spectrometry (Py-GC/MS) analyses. Two other Mediterranean forest species: Quercus suber L. and Cupressus sempervirens horizontalis L. were investigated for their distinctive flammability characteristics using thermo-gravimetric and differential thermal analyses (TG/DTA), coupled with Py-GC/MS analysis to identify the gases emitted during the exo-thermic peaks. This step aims to better understand the flammability descriptors of these species as a part of a more efficient forest management strategy by which, favoring the plantation of certain lesser flammable species in silviculture measures may protect other more flammable but economically valuable species, from the dangers of wildfires and their extreme behaviors. Mediterranean vegetation species are important VOC emitters especially when provoked by external stresses during wildfires however, some biogenic VOCs (BVOCs), more particularly sesquiterpenes, are still not thoroughly covered for their flammability characteristics, such as their lower and upper flammability limits, auto-ignition temperatures, flashpoints, etc. Such a scientific lack we found it necessary to enrich by studying the flammability limits of β-Caryophyllene, one of the most important sesquiterpenes emitted from Mediterranean vegetation. Preliminary tests for measuring the vapor pressures of β-Caryophyllene are conducted in preparation for experimenting its flammability limits in a spherical bomb as future plans. The work in this thesis should be considered as the first step in a more global approach that should provide operational firefighting staff, with a comprehensive decision-making tool capable of shaping their forest management strategies from wildfire characteristics themselves and protecting wildlands and firefighters equally from the dangers and extreme behaviors of wildfire flashovers

Texto completoThe growing desire to reduce the ecological footprint of plastic materials promotes the development of polymers and additives from renewable resources in order to limit their environmental impact. Flame retardants represent an important family of additives that play a crucial role in many fields where fire hazard is encountered. Thus this study aims at developing new flame retardant systems from biomass compounds to improve the fire behavior of polylactide (PLA), a bio-based polymer. Lignin and cellulose were chosen as pristine compounds. These compounds have been transformed into nanoparticles with adapted processes. Then, they were functionalized with phosphorous moieties or mixed with ammonium polyphosphate, and incorporated into polylactide with in internal mixer. Thermal, flammability and fire properties of these compounds were evaluated. The results obtained with some systems are promising

Texto completoHow can a few grams of lead expelled with a few grams of powder remotely take out the toughest boor? Why can the same projectile kill one and spare the other? Since the 15th century, these questions frighten the fighter, intrigue the surgeon and stir the scientific community.Crossing historic data, medicolegal reports and scientific experiments, this study tries to answer these centuries-long questions. The consulted sources are mostly based on surgical writing but also explore books dealing with weapons, ammunition, tactics, given all these factors interneve in this, something definitive, drama that is the tumultuous encounter between a projectile and the particular target that the human body is. The results are mixed and often contradictory, opposing those who think a projectile-induced wound is a common wound and those who consider the igniting mechanism has to be taken into account to study and treat its effects efficiently. This work shows, apart from these polemics, the great diversity of firearms wounding effects, no ballistic trauma being strictly comparable to another. This non-reproductible specificity, aside from scientific experiments, rules out any formal and definitive answer regarding the effects of firearms projectiles. Being shot with a bullet remains an individual adventure with unpredictable consequences

Texto completoElectrical cable sheaths are the most abundant fire load in nuclear power plants and fire is the most frequent internal aggression (one fire outbreak per year and per nuclear unit in France). A fire is threatening by two means: the heat it releases that may drive a fire growth and the smoke it yields, composed of gases and aerosols, that may be toxic and corrosive and interact with components in the area. At advanced stages, confined fires become oxygen depleted and the combustion regime shifts towards under-ventilated and vitiated combustion with the production of unburnt species leading to a higher threat. To assess the potential hazard of a confined fire, it is then of high importance to quantify the heat release, the gases and the aerosols produced by electrical cable sheaths fires in oxygen depleted conditions. To do so, a bench scale apparatus known as the controlled-atmosphere cone calorimeter (CACC) has been developed. The apparatus has been primarily qualified with PMMA plaques. Representative materials of PVC based electrical cable sheath have been formulated and manufactured in the shape of plaque samples. These materials have been characterized in terms of fire parameters (heat release rate, mass loss rate), evolved gases and evolved aerosols under different oxygen concentrations in under-ventilated conditions thanks to the CACC/FTIR/ELPI coupling. Vitiation lowers the heat release rate and decreases the fuel mass loss rate while under-ventilation increases unburnt species and aerosols production

Texto completoOmbrotrophic peatlands (bogs) are known to be Carbone sink partially because of their resistance and resilience to fire. In a global climatic change context with politics aiming toward a reduction of atmospheric Carbone emission, a quick restoration of every degrade peatlands is desirable. The Canadian horticultural industry developed a promising peatland restoration technique. More than 100 sites were restored in Canada and despite many success indicators, we still hope that restored peatlands are resistantandresilient to fire. Indeed, few studies assess an ecosystem response to a disturbance happening after restorationandnone evaluates the response to fire of restored peatlands. At the end of summer 2014, a fire occurred in a Southern Quebec bog, partially burning a ten years old restored sectoranda natural one nearby providing the first opportunity to study the response to fire of a restored peatland. This research is divided in two objectives: 1) determine if the peat accumulation potentialandplant cover are the same between the burnedandunburned parts of the restored sector one growing season after fireand2) compare the mosses strata recovery between the naturalandthe restored sectors. The phytobiomass production rate was similar between the burnedandunburned parts of the restored sectorandthe burned parts plant cover growths significantly during the first growing season after fire, even reaching a similar level as the unburned parts for some areas. Sphagnumhummocks of the restored sectors showed a better resistanceandrecovery than the one in the natural sector. Thus, this study shows a tendency to resilience to fire of restored ombrotrophic peatlands.
