Full textExtreme fires are characterized by their high intensity and rate of spread, which overwhelm firefighting resources. These phenomena result in increased damage, civilian and operational fatalities and disruption to ecosystems, human life and the economy. There are several types of extreme fires, including high-intensity fires, which are the main subject of this thesis. This type of fire presents a real risk, given the increase in its frequency and scale throughout the world. Consequently, it is very useful to assess the conditions of propagation that can trigger a high- intensity fire in order to be able to anticipate these phenomena. In addition, studying the behavior of a high-intensity fire (rate of spread, intensity and impact) can provide information to operational staff during the firefighting phase. The main aim of this thesis is to study the propagation of high-intensity fires by means of experimental fires carried out on a field scale on Corsican shrub species named 'Genista salzmannii'. These experiments were carried out during two periods (winter and autumn), in two different regions: North-West and South-West of Corsica, using an experimental protocol and technologies that make it possible to assess the dynamic and impact of these fires. Following the experiments, numerical studies were carried out using fully physical fire models based on a multiphase formulation, FireStar2D and 3D, in order to test the relevance of these propagation models in predicting the behavior of these experimental fires. The different numerical results obtained for the three terrain configurations chosen were in agreement with the experimental results. This shows that these models can be used to study other configurations without necessarily having to resort to experiments. The fire campaigns carried out were representative of high-intensity fires that occurred despite marginal propagation conditions related to low wind speeds, high fuel moisture content and relative air humidity. These experiments can also provide detailed observations, as well as input data that can be used in modelling, given that carrying out such experiments is not easy and is always subject to difficulties and constraints. The second part of the research focused on a numerical study of a "critical case" of a high- intensity fire. This fire was studied using several empirical approaches, fully physical models found in the literature, in particular FireStar2D and 3D and the simplified physical Balbi model. Several parameters were evaluated using the different approaches, including the rate of spread, the intensity of the flame front, the geometry of the front and of the flame (length and tilting). The main aim of this study was to assess not only the behavior but also the impact of this high-intensity fire on two different targets: the human body and a four level building. This made it possible to establish correlations between the total heat fluxes received by the targets as a function of their position in front of the fire. The aim was to assess the safety distance around wildland urban interfaces by considering the maximum tolerable value of thermal heat flux that can be received by the target without causing damage. The safety distances assessed using this methodology, for a firefighter and a building, are less than 50 meters. This confirms, for this configuration, the effectiveness of the value of the safety distance around buildings, set by operational experts and assumed to be equal to a minimum of 50 m in France

Full textDans un premier temps, un modèle théorique de type intégral est développé pour décrire le comportement d'un panache massique se développant en champ libre, dans un fluide ambiant au repos et non stratifié. Ce développement théorique met en évidence que les évolutions avec l'altitude des caractéristiques du panache peuvent être déduites de celle d'un paramètre unique, la "fonction panache". Dans un second temps, des simulations numériques sont réalisées à l'aide du code de calcul Fire Dynamic Simulator (FDS) dans des situations de plus en plus complexes : panache massique d'hélium en champ libre puis en milieu confiné et ventilé (type tunnel). Les résultats de simulations numériques obtenus pour un milieu confiné et ventilé sont encourageants, en bon accord avec des données expérimentales. Les résultats numériques et expérimentaux, obtenus dans le cadre d'un projet de recherche national RGC&U, permettent de mettre en lumière les mécanismes à l'origine du caractère fortement tridimensionnel d'un panache d'incendie dans un tunnel ventilé longitudinalement. Enfin, dans le cadre des essais sur maquette, les règles de similitude pour la simulation d'un panache d'incendie réel par un panache massique sont établies à partir des équations physiques. Le foyer est modélisé par le rejet d'un mélange gazeux léger air-hélium dont les caractéristiques sont ajustées afin de correctement reproduire la masse volumique des fumées d'incendie.

Full textYellow and red light running is an important cause of intersection crashes. These behaviors are more or less deliberate and influenced by different contexts. The aim of this PhD was to study factors involved in the decision making dealing with traffic lights. We examined how car drivers negotiate between safety, respect of the rules, and reducing waiting time. This thesis comprised an introduction followed by two main parts. The first part exposed theories of motivation, decision making, and time and space perception which gave the basis for the empirical research. It ended with a presentation of the problem section. The second part comprised four studies. The first one, based on the Theory of Planned Behavior (Ajzen, 1985), examined the predictors of the intention to run the yellow light. Next studies, carried out on driving simulator, investigated the influence of (study 2) social and personal context on drivers’ behavior at traffic lights, and (study 3) of stopping at lights on the travel time perception as well as the consequences of this perception for drivers’ behavior at traffic lights and for the route choice. The fourth study focused on the use of the numerosity heuristic in the choice between two itineraries depending on the number of traffic lights and the probability of stopping at the lights. For finishing this work, the results obtained were discussed and limits of the studies carried out were commented before drawing a final conclusion

Full textIn order to enhance the energy efficiency of buildings, the facades are becoming more sophisticated in both their configurations and compositions. However, the amount of fuel of these new facades is much higher than that of traditional facades. Therefore, the risk of fire spread through the facade is more important. Thus, the objective of this work is to model the fire development inside and outside of a building, taking into account different configurations and facade compositions. This experimental and numerical research has identified the parameters that increase or decrease the risk of fire spread via the façade. First, after verifying the capacity of the FDS code to model the parietal flames, a numerical study that examines the influence of the geometry of a facade fire spread was completed. Indeed, the various phenomena related to openings dimensions and / or configurations of the façade have been identified. It was therefore possible to analyze their influence on the risk of fire spread along the façade using quantities such as the heat released outside the building, the flame height and thermal actions (temperature, fluxes). Among the configurations studied are contained more or less complex geometries that can be encountered on the buildings. For example, multiple openings or "U" configurations were investigated in order to study the influence of the chimney effect on the extension of flames. Indeed, this type of configuration has already been the cause of the rapid spread fire through walls regardless of their compositions. Subsequently, an experimental study on fire spread along a combustible wall was realized with two goals. First, a series of tests was performed in order to observe propagation phenomena on a combustible façade and to collect experimental data to validate propagation models and numerical simulations in this situation. Secondly, another experimental campaign was used to study the influence of the presence of a ventilation air gap between the cladding and the wall on the spread of fire. This latter is widely used in the construction of facades. This research, both academic and applicative, has provided new information on the fire development and fire behavior along a façade, combustible or not. The numerical results demonstrate the various parameters governing the development of a fire along a façade, which facilitates the understanding of phenomena related to this issue. In addition, various tests can be used as a database for the modeling of fire spread along a combustible wall. Thus, this work contributes to the development of models of fire development and spread on buildings via the façade

Full textOne of the causes which supports large scale wildfires is the alarm precision lack. Indeed, firemen need tools able to detect fast and specify a sit of a fire. A new generation of tool is appeared : Wireless Sensor Network. In environemental monitoring, these sensors networks, having decentralized architecture and deployed in a zone, must to transmit their information, by a multi-hop communication, towards a base station. For this communication, the routing protocols attempt to carry out reliable data transmission, while testing to save the energy resources. In the problems of forest fires, the networks of sensors are able to help them firemen. However, we identify three axes for which it is necessary to provide answers : these networks, are they able to envisage, detect and follow a fire ? To answer these questions, the existing simulation tools are incomplete or unusable in our context study. In this essay, we introduce a new application, DEVS-WSN, based on a DEVS description. It allows to study performance and the deployment stratégies of the Wireless Sensor Networks. Moreover, we present a new algorithm of routing VOX, which improves the energy saving and increases lifetime of the network in the particular context of destroying phenomenons. We supplement this theoretical study by a test of Wireless Sensor Network on real fire. All these work advances the conditions of use of Wireless Sensor Network in the fire problems
