▼ Population explosion and the associated anthropogenic activities generate huge amounts of different wastes that adversely affect the physical environment of Addis Ababa City. This situation is not different for Arada Sub-city, which is one of the oldest and the central part of the city, where the concern of this study has focused. The current estimated population of the subcity is 350,000 people. The sub-city has been established as part and parcel of the city in 2003 and has got a wide range of power and various urban service activities to be provided for the residents. Often a discrepancy exists between the growing population and the increasing demand for the urban services on one hand and the capacity of the local government to provide these services on the other hand. This study has focused on, household solid waste management service delivery, one of the urban services provided by the sub-city and the role of the stakeholders in this particular activity. In this study, both quantitative and qualitative descriptions were used to show the performance of the sub-city in delivery of the household solid waste management service. The role and performance of the sub-city’s agent was assessed in terms of the service it provides, institutional and resource capacity, working relations with stakeholders mainly with the MSEs, issues of awareness raising and user participation in the sub-city were attempted to be included. The findings of the study revealed that household solid waste management service in the sub-city is provided below the required quality or has a poor status. According to the survey results, the inadequate organization, lack of material and human resources, unfair distribution of containers, lack of proper support for the private sector, lack of awareness raising and community participation are some of the factors that account for poor solid waste management service delivery in the sub-city. Finally, results of the study indicate that there is so much to be done in order to improve the service provision. Thus, there is a need to create driving motives into the community to use integrated sustainable solid waste management strategies by promoting public- privatepartnership in the area of solid waste management service delivery in the sub-city.

Notre compréhension de la structuration des chaînes trophiques pélagiques du Paléozoïque inférieur, mise en place lors des évènements d’« explosion Cambrienne » et de « Grande Biodiversification Ordovicienne » et qui a abouti à la mise en place des écosystèmes marins à « caractère moderne », reste encore très fragmentaire. Nous nous intéressons ici à comprendre les origines et la dynamique de paléobiodiversité des Radiolaires polycystines, composantes biotiques clefs du plancton hétérotrophe, dans le but de mieux comprendre le calendrier et la dynamique de diversification du plancton au cours du Paléozoïque inférieur. La découverte de nouveau matériel provenant des montagnes de l’Altaï (Sibérie) apporte de nouvelles données sur l’enregistrement fossilifère des premiers radiolaires biominéralisés avec l’identification des plus anciens représentant de la famille des Archéoentactinidae d’âge Botomien. Des études menées sur du matériel de Terre-Neuve et d’Australie ont permis de caractériser l’ensemble des changements biotiques intervenus au sein des assemblages à radiolaires à l’aube de la révolution planctonique mais également de préciser la répartition paléogéographique des radiolaires au Cambrien supérieur. Une étude taxonomique menée sur un échantillon provenant du Kazakhstan a également permis la découverte d’un nouvel assemblage à radiolaire enrichissant considérablement notre connaissance de la diversité des radiolaires à l’Ordovicien moyen.

Our understanding of the structuration of Lower Paleozoic pelagic trophic chains during the ‘Cambrian Explosion’ and the ‘Great Ordovician Biodiversification Event’, which has lead to the establishment of modern marine ecosystems, is still very fragmentary. We are here interested in understanding the paleodiversity dynamics of polycystines Radiolaria planctonic group, a key biotic component of the heterotrophic plankton, in order get a better idea of the timing and dynamics of plankton diversification at the Lower Paleozoic. The discovery of new material from the Altai Mountains (Siberia) brings new data on the fossil record of the first biomineralized radiolarians with the identification of the oldest representatives of the Archeoentactinidae family dated of a Botomian age. Study conducted on Newfoundland and Australian material allowed us to characterize precisely the various biotic changes undergone by radiolarians during the Cambrian-Ordovician transition, at the dawn of the planktonic revolution but also to precise their paleogeographic distribution at the Late Cambrian. A detailed taxonomic study conducted on a Kazakhstanian sample has allowed us to describe a new radiolarian assemblage enriching considerably our knowledge on the radiolarian diversity at the middle Ordovician.

▼ Dust explosion hazards in areas where combustible dusts are found have caused loss of life and halted business operations in some instances. The elimination of secondary dust explosion hazards, i.e. reducing dust dispersion, can be characterized in shock-tubes to understand shock-dust interactions. For this reason, a new shock-tube test section was developed and integrated into an existing shock-tube facility. The test section has large windows to allow for the use of the shadowgraph technique to track dust-layer growth behind a passing normal shock wave, and it is designed to handle an incident shock wave up to Mach 2 to impersonate real-industry scenarios. The characterization experiments presented herein demonstrate the advantages of the authors? test techniques toward providing new physical insights over a wider range of data than what have been available heretofore in the literature. First, the effect of shock strength on the dust entrainment process was explored by subjecting limestone dust to Mach numbers ranging from 1.10 to 1.60. Also, the effect of dust-layer thickness on the entrainment process was observed by performing tests with two different layer depths, namely 3.2- and 12.7-mm thicknesses. New data were collected to develop correlations between the shock strength and the dust entrainment height as a function of time for each layer depth. The longer observation time and higher camera framing rates led to the discovery of trends not previously observed by earlier studies, such as a clear transition time between the early, linear growth regime and a much-slower, average growth regime. This second regime is however accompanied by surface instabilities that can lead to a much larger variation in the edge of the dust layer than seen in the early growth regime. In addition, for the linear growth regime, there was no significant difference in the dust-layer height growth between the two layer thicknesses; however, the larger thickness led to higher growth rates and much larger surface instabilities at later times. Next, we conducted experiments to elucidate the effect of particle size and size polydispersity on dust cloud formation phenomena behind blast waves. Through systematic modification of the span of the particle size distribution, the striking effect of polydispersity on the entrainment process was demonstrated. Moreover, correlations between linear dust rise rate and particle size and size polydispersity have been developed. Finally, recommendations for numerical modelers of this field and NFPA 654, Standard for the Prevention of Fire and Dust Explosions from the Manufacturing, Processing, and Handling of Combustible Particulate Solids are provided for developing a better dust explosion hazard assessment tool.

▼ Detection of xenon radioisotopes (radioxenons) has proven to be an important method for detecting nuclear explosions and is particularly well suited for detecting undeclared underground testing. The radioxenon isotopes ¹³¹mXe (t₁/₂ = 11.934 d), ¹³³mXe (t₁/₂ = 2.19 d), ¹³³Xe (t₁/₂ = 5.243 d) and ¹³⁵Xe (t₁/₂ = 9.14 h) are produced in significant amounts in nuclear explosions and are of particularly high-value in identifying such events and thus are the focus of current radioxenon detection systems. The main objective of this dissertation is to design, build and test a new radioxenon detection system to study the response of CdZnTe (CZT) detectors to xenon radioisotopes in order to support the CTBT for discovering clandestine nuclear weapon tests. This prototype detection system was intended to be small and compact with minimal number of channels which reduces complexity, power and size and still can achieve good energy resolution at room temperature compared with other scintillator-based radioxenon detectors. The prototype design uses two CZT crystals for this purpose, with the ultimate goal of using six CZT crystals for optimum geometric efficiency. The system measures xenon radioisotopes through beta-gamma coincidence detection between the two detection elements. The CZT-based detection system was characterized with radioactive lab sources and four radioxenons produced in the OSU's TRIGA reactor. The detection system offers excellent energy resolution and background count rate compared with scintillator-based beta-gamma coincidence detectors currently in operation at the IMS stations. The detection system was also simulated using MCNP to understand the response of the system to radioxenons of interest. PTRAC card was used for this purpose to find the track of beta/conversion electrons and gamma/X-rays in each CZT detector. The MCNP simulations were compared with the measurement results and shows very good consistency. The minimum detectable concentration (MDC) of this system for ¹³³Xe is estimated to be less than the requirement set by the IMS (1 mBq/m³). Our estimations also show that by increasing the number of CZT crystals to 6, the MDC of all radioxenons will be improved to less than 1 mBq/m³ which is comparable with the most sensitive radioxenon detection systems currently in operation.

▼ Dans le cadre des opérations de démantèlement des centrales nucléaires UNGG (Uranium Naturel Graphite Gaz), l’occurrence de phénomènes indésirables, tels que l’inflammation et l’explosion de poudres, ne peut pas être systématiquement exclue. Plus particulièrement, le risque d’inflammation et d’explosion de poussières de graphite, pur ou mélangé avec des impuretés métalliques telles que des particules de magnésium ou de fer, nécessite d’être évalué de façon plus approfondie. Les travaux de cette thèse s’inscrivent donc dans ce contexte et ont deux objectifs principaux : l’évaluation expérimentale de l’explosivité et sa modélisation. 1. L’évaluation expérimentale de l’explosivité des poudres d'intérêt a été réalisée tant en termes de sensibilité à l’inflammation, en couche et en nuage, que de sévérité à l’explosion. En effet, les caractéristiques explosives d’une poussière ou d’un mélange sont fortement influencées par plusieurs paramètres. Ils dépendent d’une part des conditions opératoires, tels que la turbulence, la température et l'énergie d’inflammation, et d’autre part, des propriétés physico-chimiques et de la composition des matériaux. Cette étude s’est focalisée sur des poudres pures de graphite, de magnésium et de fer de taille micrométrique et sur leurs mélanges, dans un éventail de concentrations d’intérêt industriel. Nous avons constaté que l’introduction de métaux peut changer en premier lieu l’étape limitant la vitesse de combustion du graphite. Tout d’abord, les phénomènes cinétiques limitant de l’oxydation du graphite ont été distingués de ceux des métaux (respectivement, réaction hétérogène ou flamme de diffusion gazeuse). En deuxième lieu, il est apparu que la flamme peut être épaissie par la présence du rayonnement lors de la combustion du métal, alors que ce phénomène est négligeable pour le graphite pur. Enfin, la turbulence initiale du nuage de poussière peut être elle aussi modifiée par l'ajout d'une deuxième poudre en vue des caractéristiques granulométriques et de densité différentes. Une étude paramétrique a donc été réalisée afin d'évaluer l'explosibilité des mélanges considérés en prenant en compte les effets de l'humidité relative des poudres, de leur distribution granulométrique, de la puissance de la source d'ignition, de la turbulence initiale du milieu et de la composition. Pour ce faire, nous avons utilisé à la fois des appareils et des technologies conventionnelles, tels que la sphère de 20 litres, la vélocimétrie par images de particules et la thermogravimétrie, mais également des nouvelles installations dédiées à la caractérisation des écoulements turbulents transitoires lors de la dispersion des poudres dans la sphère d'explosion et à l’étude de la propagation d’une flamme en milieu semi-confiné. Il a été clairement démontré que l'ajout de poudres métalliques influence l'aptitude à enflammer le nuage de poussière. L'énergie et la température minimale d'inflammation diminuent fortement lorsque le magnésium est ajouté au graphite ; ce phénomène est moins sensible pour les particules… Advisors/Committee Members: Dufaud, Olivier (thesis director), Perrin, Laurent (thesis director).

▼ In development projects, designers should take into consideration the possibility of a vapor cloud explosion in the siting and design of a process plant from day one. The most important decisions pertinent to the location of different process areas, separation between different areas, location of occupied buildings and overall layout may be made at the conceptual stage of the project. During the detailed design engineering stage the final calculation of gas explosion loads is an important activity. However, decisions related to the layout and location of occupied buildings at this stage could be very costly. Therefore, at the conceptual phase of the development project for a hydrocarbon facility, it would be helpful to get a picture of possible vapor cloud explosion loads to be used in studying various options. This thesis presents the analytical parameters that are used in vapor cloud explosion risk analysis. It proposes a model structure for the analysis of vapor cloud explosion risks to buildings based on exceedance methodology. This methodology was developed in a computer program which is used to support this thesis. The proposed model considers all possible gas release scenarios through the use of the Monte Carlo simulation. The risk of vapor cloud explosions can be displayed using exceedance curves. The resulting model provides a predictive tool for vapor cloud explosion problems at the early stages of development projects, particularly in siting occupied buildings in onshore hydrocarbon facilities. It can also be used as a quick analytical tool for investigating various aspects of vapor cloud explosions. This model has been applied to a case study, a debutanizer process unit. The model was used to explore the different alternatives of locating a building near the facility. The results from the model were compared to the results of other existing software to determine the model validity. The results show that the model can effectively examine the risk of vapor cloud explosions. Advisors/Committee Members: Mannan, M. Sam (advisor), Barrufet, Maria A.

▼ Dans le contexte actuel de croissance continue de la demande mondiale en combustible fossile, la sécurité de la production, du transport, ainsi que du stockage de l'énergie est un défi majeur de ce début de XXIème siècle. Les produits manipulés étant extrêmement volatils et inflammables, les éventuelles fuites qui peuvent survenir malgré les lourdes mesures de sécurité mises en place, peuvent engendrer des explosions désastreuses. Il existe donc un fort besoin d'être capable de prédire ces explosions afin de limiter les dégâts potentiels et d'assurer la sécurité des personnes et des biens. Dans cette optique, l'augmentation régulière des puissances de calcul permet à la CFD (Computational Fluid Dynamics) de se présenter comme une alternative intéressante aux expériences qui peuvent s'avérer couteuses et dangereuses. Les explosions sont des phénomènes multi-physiques qui sont principalement dirigés par la turbulence et la combustion et qui prennent place sur une très large gamme d'échelles nécessitant ainsi d'être modélisées. Aujourd'hui, des codes basés sur une approche URANS (Unsteady Reynolds Averaged Navier Stokes) sont généralement utilisés afin de simuler des explosions de gaz dans des configurations à échelle industrielle. Cependant, l'émergence de la LES (Large Eddy Simulation), qui a déjà montré son potentiel à donner des prédictions plus fiables que le URANS sur des configurations instationnaires complexes, ouvre de nouvelles perspectives pour le domaine de la sécurité explosion. Le but principal de cette thèse est d'évaluer l'apport des méthodes LES et de développer une méthodologie pour la prédiction des phénomènes réactifs turbulents transitoires que sont les explosions. Tout au long de cette étude, un intérêt particulier a été porté à l'approfondissement de la compréhension des phénomènes d'explosion ainsi qu'à la mise en valeur des points cruciaux de modélisation qui permettent une reproduction correcte des phénomènes considérés. Notre approche peut alors se résumer en deux temps : - Dans un premier temps nous nous sommes concentrés sur l'étude LES des déflagrations dans une chambre de combustion de petite échelle : la configuration expérimentale de l'Université de Sydney. La LES associée à un modèle de flamme épaissie a ainsi été appliquée à cette configuration à l'aide du code AVBP (développé par le CERFACS et l'IFP-EN) et a permis de mettre en place une méthodologie de calcul. Une étude de Quantification d'Incertitude (UQ) a ensuite été réalisée sur ces simulations afin d'évaluer la fiabilité de ces résultats, ce qui est primordial dans ce contexte d'étude de sécurité. - Dans un second temps, le but a été d'extrapoler les résultats obtenus sur la configuration de petite échelle à des configurations de plus grande échelle, plus représentatives des configurations industrielles réelles de plateformes pétrolières ou de dépôts de carburants qui constituent l'objectif final visé. Une campagne expérimentale a ainsi été lancée afin de construire des répliques de la configuration de Sydney à des échelles plus… Advisors/Committee Members: Poinsot, Thierry (thesis director), Vermorel, Olivier (thesis director).

▼ Phreatic and hydrothermal eruptions often occur with little or no warning representing a significant hazard within geothermal regions. These violent eruptions occur at a range of temperatures and pressures within varying rock types. A range of mechanisms including heating or decompression, allows hydrothermal/supercritical fluid to rapidly flash to steam, expanding and shattering the surrounding rock to produce an eruption, with no direct magmatic influence. These eruptions are highly variable resulting in the current wide ranging classification schemes, many of which are based on characteristics that are hard to observe and define. This has resulted in confusing nomenclature with many different terms used to describe the same eruptive phenomena. Here a new classification scheme is presented, based on the easily definable features of eruption size, trigger type (natural or anthropogenic) and geological setting (volcanic or hydrothermal). This ultimately produces a classification dividing the eruptions into either phreatic, where magma interacts with cold water but no juvenile material is erupted; or hydrothermal where eruption occurs from an already heated hydrothermal system. Examples are then provided for each classification type. Previous studies have focused exclusively on either physical characteristics of eruptions, small scale experimental modelling of trigger processes or mathematical modelling of various eruption characteristics. Here, a new experimental procedure has been developed to model phreatic fragmentation, based on shock tube experiments for magmatic fragmentation by Alidibirov and Dingwell (1996). Water saturated samples are fragmented from a combination of argon gas overpressure and steam flashing within vesicles. In this thesis, these experimental results have been integrated with the physical characteristics of porosity, permeability and mineralogy to create two new models of phreatic fragmentation. Firstly a generalised model to explain fragmentation processes and secondly a specific model describing the eruption forming Lake Okaro, within the Taupo Volcanic Zone of New Zealand. These models were developed with the overall aim to improve understanding of these eruption types, ultimately improving future hazard modelling. Experiments were performed on Rangitaiki ignimbrite, through which the Okaro eruption occurred. In order to evaluate alteration effects, both unaltered ignimbrite and hydrothermally altered ignimbrite samples were analysed. Experiments were performed at room temperature and 300°C with pressures from 4 to 15 MPa, to reflect likely geothermal conditions while also assessing the effect of liquid water on fragmentation. Results indicate that within these samples 5 to 8 MPa of decompression is required to trigger an eruption, fitting well with the previously identified trend between decompression and porosity for magmatic samples. The fragmentation front propagates through the sample at speeds ranging between 14 m/s to 42 m/s, increasing with higher applied pressures and…

▼ A smoke explosion is generally considered as a deflagration of the accumulated unburned fuel inside a closed compartment. However, the term smoke explosion has been widely misused for decades with a great deal of confusion, and very little research has been done towards this topic. The purpose of this research is to study the smoke explosion phenomenon in much more detail through the development of a fire scenario under various experimental conditions including ventilation size, fuel elevation and fuel mass, so that a more comprehensive understanding of this phenomenon can be achieved. A total of twenty experiments are carried out including both exploratory and final experiments. Thirteen experiments result in smoke explosions, among which there are five experiments result in more than one smoke explosion. A phenomenon referred as smoldering decay is observed in all experiments with smoke explosions, making it one of the precursors of the smoke explosion phenomenon. The smoldering decay is often indicated by an exponential decay of the temperature and is caused by the low oxygen concentration within the compartment. Based on the analysis, it is found that the vent size must be at least 50 mm in diameter in order for smoke explosions to occur. The fuel elevation has no influence on the occurrence of the smoke explosion. However when the fuel is placed near the ceiling, the temperature, the mass flow rate and the heat release rate are all lowered significantly. The size of the fuel also has no significant influence except for the duration of the experiment. The concentration of CO is scattered in the range of 1.9% and 4.3% when explosions occur. Hence, the accumulation of CO is considered not to be the direct cause for the smoke explosion. The triggering factor for smoke explosions is believed to be the flammable limit formed by the mixture of hydrocarbon and CO. The pressure difference caused by the explosion inside the compartment has to be at least 27 Pa for it to be considered as a smoke explosion.

Le Cambrien et l'Ordovicien étaient une période de changements importants dans l'histoire de la vie, lorsque les embranchements animaux actuels ont émergé et des écosystèmes de style moderne se sont développés au cours de l'explosion cambrienne et la radiation ordovicienne. Ces deux événements sont au centre du projet RALI (Rise of Animal Life). Dans le cadre de ce projet, ce travail de thèse se focalise sur trois sujets clés concernant des palynomorphes par rapport aux biodiversifications cambro-ordoviciennes : 1) La biodiversité des acritarches du Cambrien, 2) les palynomorphes de la formation de Fezouata (Ordovicien Inférieur, Maroc), et 3) les palynomorphes inhabituels (« Small Carbonaceous Fossils », SCF) du Lagerstätte de Winneshiek (Ordovicien Moyen, Iowa, Etats-Unis). Pour l'analyse de la biodiversité des acritarches, les données d'apparition des espèces et des genres des acritarches au cours du Cambrien sont assemblées et divers indices de diversité sont calculés. Les résultats montrent un lien possible entre les biodiversités des acritarches et des invertébrés marins pendant l'explosion cambrienne, mais aussi un biais sérieux dans les données des acritarches. Des échantillons provenant du Konservat-Lagerstätte (un site avec des fossiles à conservation exceptionnelle) de Fezouata, qui témoigne des premiers stades de la radiation ordovicienne, et du sous-sol ont délivré des acritarches et chitinozoaires abondants et diversifiés. Leurs implications sont discutées. Les schistes de Winneshiek sont riches en vestiges organiques, y compris d'éventuelles mandibules et plaques filtrantes des crustacés, ainsi que des « algues » filamenteuses avec des cellules géantes.

The Cambrian and Ordovician were times of important changes in the history of life, as the present animal phyla emerged and modern-style ecosystems developed during the so-called Cambrian explosion and the Great Ordovician Biodiversification Event. These two events are the focus of the project RALI “The Rise of Animal Life”. As a part of this project, the present thesis concentrates on three key topics regarding palynomorphs in relation to the Cambro-Ordovician biodiversifications: 1) The biodiversity of Cambrian acritarchs, 2) palynomorphs from the Fezouata Formation (Lower Ordovician, Morocco), and 3) unusual palynomorphs (Small Carbonaceous Fossils, SCFs) from the Winneshiek Lagerstätte (Middle Ordovician, Iowa, USA). For the analysis of acritarch biodiversity, occurrence data of acritarch species and genera during the Cambrian are assembled from the literature and various diversity indices are calculated. The results indicate a possible link between the biodiversities of acritarchs and marine invertebrates during the Cambrian explosion, but also a heavy bias in the acritarch data. The Fezouata Formation bears exceptionally preserved biotas, which document the early stages of the GOBE. Samples from this Konservat-Lagerstätte (site yielding exceptionally preserved fossils) and from the sub-surface of the Fezouata Formation yielded abundant and…

▼ The Cambrian explosion bisects the history of life, separating relatively simple pre-Cambrian life from a complex and diverse Cambrian fauna. Due to the paucity of the body-fossil record, trace fossils often offer the only available insight into these evolutionary milestones, representing a continuous record through the late Ediacaran-early Cambrian. The Chapel Island Formation (CIF) of the Burin Peninsula, Newfoundland, provides an exceptional record of these innovations. Currently, the Global Boundary Stratotype Section and Point (GSSP) for the basal Cambrian boundary is located 2.4 m above the base of member 2 of the CIF, delineated by the lowest observed appearance of the Treptichnus pedum Ichnofossil Assemblage Zone (IAZ). Currently, researchers are facing difficulties when attempting to correlate with a few sections worldwide, and a formal revision of the boundary has been proposed. We hypothesize that a revision of the ichnotaxonomy of the GSSP with an emphasis on trace fossil functional morphology may better illustrate evolutionary innovations at the Ediacaran-Cambrian boundary. In turn, this revised ichnotaxonomy may provide further support for the position of the Ediacaran-Cambrian GSSP. Through a bed-by-bed study, the ichnotaxonomy of the T. pedum IAZ was revised, and a stratigraphic section was measured. Twenty ichnospecies comprising thirteen ichnogenera were observed (Figure 0.1). The ichnospecies were grouped into five ichnoguilds, which were used to conduct an ecospace analysis of the section. The ichnofauna reveled a more gradual appearance of ichnofossil diversity at the boundary, and a more protracted transition between Ediacaran and Cambrian ecosystems than previously envisioned. The T. pedum IAZ in the CIF marks the appearance of novel methods of interacting with the substrate as documented by sub-horizontal branching burrows (treptichnids), equilibrium structures (Bergaueria isp.), and complex vertical burrows (Gyrolithes scintillus). Additionally, it marks the evolution of novel body plans, as revealed by the presence of arthropod scratch marks (Dimorphichnus cf. obliquus). However, remnants of Ediacaran matground ecology are also present. Farming feeding styles are utilized by the Gyrolithes scintillus ichnoguild, and mat grazing remains a common feeding style. These ichnotaxa provide valuable insight into the very beginnings of vertical, penetrative burrowing. They further illuminate the depth and rate at which this new lifestyle evolved, and shed light on the evolution of three-dimensional burrowing.

▼ Certain goods have properties that may cause severe effects in case of an accident during transport. The most striking events are the occurrence of fire and explosions. Since tunnels are isolated environments, many casualties and severe damage are to be expected in case of an explosion. Although the probability for such an event is rather small, restrictions apply for tunnels concerning transport of hazardous goods. As a result of these restrictions alternative routes have to be used, often resulting in long detours that sometimes cross built-up areas, which is also undesirable. Therefore, at some locations it is desired to ease the restrictions for tunnels. For a recent immersed tunnel project requirements concerning explosion loads were stated. A static pressure of 500 kPa and a suction of 300 kPa should be taken into account. The nature of the requirement was not clear however. During the tender phase, BAM Infraconsult concluded that large thicknesses for the slabs and walls of the tunnel are required. The concrete elements, of which an immersed tunnel is composed, should float during transport, while in the final situation a large deadweight is favorable in order to prevent uplift. These are contrary demands that result in a very delicate balance. The requirement for the explosion load interferes with this balance and makes it difficult to comply with all demands efficiently if traditional design methods are applied. This research is at first initiated in order to evaluate the recently stated statically defined requirement concerning explosion loads. Secondly, a technical feasibility study into the design of an explosion resistant immersed tunnel is performed. In order to investigate the effect of explosion loads, a simplified analytical model was developed whereby the structure is divided into several elements that are schematized as single degree of freedom mass spring systems. Furthermore, the dynamic module of the finite element code Plaxis was used to perform more advanced calculations. Both models were used in the evaluation of the requirement and technical feasibility study. It is concluded that the representative explosion load is due to a LPG Boiling Liquid Expanding Explosion (BLEVE). The order of magnitude that has to be taken into account is obtained from recent research into this topic by TNO. Although the static requirement of 500 kPa pressure and 300 kPa suction is already hard to comply with, the order of magnitude is too small compared to the representative dynamic BLEVE Load according to TNO. The representative load according to TNO is used for the technical feasibility study. Several solutions, with respect to reduction of the load, dissipation of energy and application of alternative materials are considered. Exploring calculations were performed for promising solutions in order to judge the technical feasibility. It is concluded that the application of separate tubes provides an efficient structural solution. Since the vehicles transporting the dangerous goods are isolated from the regular… Advisors/Committee Members: Vrijling, J.K., Bakker, K.J., Van der Horst, A.Q.C., Hakkaart, C.J.A., Wolsink, G.M., BAM Infraconsult bv.

▼ Two experiments were performed to investigate the interaction of a combustion wave with porous media. The first experiment was performed in a 1.22m long, 76mm wide, and 152mm high horizontal channel with a nitrogen-diluted stoichiometric methane-oxygen mixture at initial pressures of 20-50kPa. A layer of 12.7mm diameter ceramic-oxide spheres was placed along the bottom to partially obstruct the channel, leaving a gap of free space above. For a fixed gap height the bead layer thickness had very little effect on explosion propagation. For a fixed bead layer thickness the explosion propagation was strongly influenced by the gap height. For example, a 31% nitrogen diluted mixture at room temperature resulted in DDT for a gap height of 38mm at initial pressures of 30-50 kPa, but not for 109mm over the same pressures. The gap above the bead layer permits DDT as long as the gap height is larger than one detonation cell width. Propagation of the detonation wave over the bead layer is possible if the gap height can accommodate at least two detonation cells. For a 38mm gap, velocity measurements and sooted foil imprints indicate that the detonation undergoes successive failure and re-initiation, referred to as “galloping” in the literature. In the second experiment, the head-on collision of a combustion front with a layer of 3 and 12.7mm diameter ceramic-oxide spheres was investigated in a 61cm long, 76.2mm diameter vertical tube for a nitrogen-diluted stoichiometric ethylene-oxygen mixture at initial pressures of 10-100kPa. Four orifice plates were placed at the ignition end to accelerate the premixed flame to a “fast-flame” or a detonation wave. For fast-flames pressures recorded at the bead layer face were up to five times the reflected CJ detonation pressure. This explosion iv developed by two distinct mechanisms: a) shock reflection off the bead layer face and b) shock transmission into the bead layer and subsequent explosion therein. The measured explosion delay time (time after shock reflection from the bead layer face) was found to be independent of the incident shock velocity. Thus, it was shown that explosion initiation is not the direct result of shock reflection but is more likely due to the interaction of the reflected shock with the trailing flame. The bead layer was found to be very effective in attenuating the explosion and isolating the tube endplate.

On s'intéresse à la fragmentation d'objets cohésifs au travers d'un ensemble d'expériences modèles. Dans une première expérience, on force l'extension radiale d'un anneau formé de grains cohésifs (billes magnétiques ou billes de polymères liées par des ponts liquides). Sous l'effet de l'extension, les grains se séparent, puis, à cause de la cohésion, ils entament une dynamique d'agrégation qui conduit à la formation de fragments de tailles diverses. On montre que la distribution des tailles de fragments ainsi formés converge vers une loi de distribution Gamma et on propose un modèle expliquant l'évolution auto-similaire de la distribution. Dans un deuxième temps, on introduit une distribution d'intensité des liaisons entre les grains. La fragmentation en présence de ces "défauts" conduit à une distribution des tailles de fragments plus large, mais dont la loi est conservée. Dans une dernière étude, une coque sphérique composée de liquide est forcée à s'étendre par la combustion d'un mélange de gaz réactif emprisonné à l'intérieur de celle-ci. La distribution des tailles des gouttes qui en résulte obéit à la même famille de lois de distribution que celles observées pour les anneaux composés de grains cohésifs. Dans cette dernière expérience, le rôle des défauts est joué par les instabilités hydrodynamiques se développant sur la surface de la coque liquide au cours de son extension. Ainsi la largeur de la distribution des tailles de gouttes dépend de la vigueur de l'extension de la coque liquide.

We are studying the fragmentation of cohesive objects through a set of model experiments. In a first experiment, we force the radial extension of a ring made of cohesive grains (magnetic beads or polymer beads bonded with liquid bridges). Because of the extension, the grains separate from each other, then, because of the cohesion, start an aggregation dynamic leading to the formation of fragments of different sizes. We show that the distribution of the fragment sizes formed in this way converge to a Gamma law distribution and we propose a model explaining the self-similar evolution of the distribution. On a second part we introduce a distribution of intensities of the bonds between the grains. The fragmentation in the presence of "defects" leads to a broader size distribution, with the same law. In a last study, a spherical shell composed with liquid is forced to extend by the combustion of a reagent mixture of gas confined inside. The drop size distribution observed is conform to the same family of distribution laws found for the rings composed with cohesive grains. In this last experiment the role of defects is played by the hydrodynamic instabilities developing on the surface of the liquid shell under extension. Thus the broadness of the drop size distribution depends on the strength of extension of the liquid shell.

▼ Bisher ist bei forensischen Untersuchungen von Explosionen die Rückverfolgung der verwendeten Sprengstoffe begrenzt, da das Material in aller Regel bei der Explosion zerstört wird. Die Rückverfolgung von Sprengstoffen soll mit Hilfe von Identifikations-Markierungssubstanzen erleichtert werden. Diese stellen einen einzigartigen Code dar, der auch nach einer Sprengung wiedergefunden und identifiziert werden kann. Die dem Code zugeordneten, eindeutigen Informationen können somit ausgelesen werden und liefern der Polizei bei der Aufklärung weitere Ansätze.rnZiel der vorliegenden Arbeit ist es, das Verhalten von ausgewählten Seltenerdelementen (SEE) bei Explosion zu untersuchen. Ein auf Lanthanoidphosphaten basierender Identifikations-Markierungsstoff bietet die Möglichkeit, verschiedene Lanthanoide innerhalb eines einzelnen Partikels zu kombinieren, wodurch eine Vielzahl von Codes generiert werden kann. Somit kann eine Veränderung der Ausgangszusammensetzung des Codes auch nach einer Explosion durch die Analyse eines einzelnen Partikels sehr gut nachvollzogen und somit die Eignung des Markierungsstoffes untersucht werden. Eine weitere Zielsetzung ist die Überprüfung der Anwendbarkeit der Massenspektrometrie mit induktiv gekoppeltem Plasma (ICP-MS) und Partikelanalyse mittels Rasterelektronenmikroskopie (REM) für die Analyse der versprengten Identifikations-Markierungssubstanzen. rnDie Ergebnisbetrachtungen der ICP-MS-Analyse und REM-Partikelanalyse deuten zusammenfassend auf eine Fraktionierung der untersuchten Lanthanoide oder deren Umsetzungsprodukte nach Explosion in Abhängigkeit ihrer thermischen Belastbarkeit. Die Befunde zeigen eine Anreicherung der Lanthanoide mit höherer Temperaturbeständigkeit in größeren Partikeln, was eine Anreicherung von Lanthanoiden mit niedrigerer Temperaturbeständigkeit in kleineren Partikeln impliziert. Dies lässt sich in Ansätzen durch einen Fraktionierungsprozess in Abhängigkeit der Temperaturstabilität der Lanthanoide oder deren Umsetzungsprodukten erklären. Die der Fraktionierung zugrunde liegenden Mechanismen und deren gegenseitige Beeinflussung bei einer Explosion konnten im Rahmen dieser Arbeit nicht abschließend geklärt werden.rnDie generelle Anwendbarkeit und unter Umständen notwendige, komplementäre Verwendung der zwei Methoden ICP-MS und REM-Partikelanalyse wird in dieser Arbeit gezeigt. Die ICP-MS stellt mit großer untersuchter Probenfläche und hoher Genauigkeit eine gute Methode zur Charakterisierung der Konzentrationsverhältnisse der untersuchten Lanthanoide dar. Die REM-Partikelanalyse hingegen ermöglicht im Falle von Kontamination der Proben mit anderen Lanthanoid-haltigen Partikeln eine eindeutige Differenzierung der Elementvergesellschaftung pro Partikel. Sie kann somit im Gegensatz zur ICP-MS Aufschluss über die Art und Zusammensetzung der Kontamination geben. rnInnerhalb der vorgenommenen Untersuchungen stellte die bei der ICP-MS angewandte Probennahmetechnik eine ideale Art der Probennahme dar. Bei anderen Oberflächen könnte diese jedoch in Folge der in verschiedenen…

Depuis plusieurs années déjà, nombre d’applications industrielles impliquant des nanomatériaux ont vu le jour mais les connaissances relatives aux dangers de ces nouveaux matériaux sont actuellement assez restreintes. Le développement de ces nouveaux produits ne pouvant se poursuivre sans une évaluation approfondie des risques pour l’environnement et au poste de travail, les dangers relatifs aux nanoparticules doivent être évalués. La toxicité potentielle de ces nouveaux matériaux est souvent mise en avant. Néanmoins, les risques d’incendie et d’explosion ne doivent pas être négligés. Centrées essentiellement sur les poudres de taille micrométrique, les données de la littérature ne permettent pas, en effet, à l’heure actuelle, d’évaluer la probabilité et la gravité d’une explosion de nanopoudres. Dans ce contexte, la sensibilité à l’inflammation et la sévérité d’explosion de nanomatériaux pulvérulents typiques ont été évaluées ainsi que la validité des appareillages et procédures standards, habituellement utilisés lors d’une telle démarche. Enfin, la méthodologie adoptée afin d’évaluer les risques d’inflammation et d’explosion d’une installation de production de nanopoudres et de sécuriser au mieux la santé des travailleurs exposés aux nanoparticules est illustrée aux travers de deux exemples. Cette démarche pourra servir de base à de futures analyses de risques concernant les produits nanostructurés, exercice qui va devenir indispensable et de plus en plus fréquent au vu du contexte économique et réglementaire

In the industrial and research fields, nanomaterials provides a growing interest and many industrial applications have already been developed in the last years. However, knowledge about the hazards related to these new materials is currently limited. As safe nanomaterial production cannot be permitted without a deeper evaluation of environmental and occupational hazards, hazards related to nanoparticles have to be evaluated. One often thinks about the potential toxicity of nanoparticles. However, dust fire and explosion should not be neglected when the dusts are combustible, which may often be the case. So far, literature studies concerning the evaluation of explosion and flammability risks of powders were essentially carried out on micron-sized materials and do not enable in fact to evaluate fire and explosion risk probabilities and gravities of nanopowders. The main goal of this work is to study explosion and ignition risks related to nanopowders. In particular, the evaluation of the explosion sensitivity and severity of typical nanomaterials has been studied as well as the validity of the existing analytical and methodological tools designed to evaluate dust ignition and explosion hazards. This work also deals with the methodology applied to a plant and to a laboratory in order to define the best safety barriers which were positioned to ensure the best occupational safety level to all workers and evaluate in a good way the ignition and explosion risks related to the use and production of fluffy…

La sensibilité et la sévérité d'explosion des différents mélanges gaz/vapeur-poussière ont été étudiées grâce à des dispositifs standards (sphère de 20 L, tube de Hartmann). Les spécificités des explosions de mélanges hybrides gaz/poussière ont été mises en évidence. En fait, même pour des concentrations de gaz inférieures à la limite inférieure d'explosivité (LIE), la probabilité d'inflammation et la gravité d'explosion peuvent être considérablement augmentées, ce qui permettra notamment de conduire à de grands changements dans la détermination des zones ATEX. Il a été, par exemple, démontré que ces mélanges peuvent être explosifs même lorsque la concentration en poudre et la concentration en vapeur sont respectivement en dessous de la concentration minimale explosive et de la LIE. En outre, des effets de synergie ont été observés et la vitesse de montée en pression de mélanges hybrides peut être supérieure à celles des gaz purs. Les origines de ces spécificités ne doivent pas être recherchées dans la modification d'un paramètre unique, mais peuvent probablement être attribuées aux effets combinés sur l'hydrodynamique (propagation de la flamme), le transfert thermique et la cinétique de combustion. Des expériences ont été menées afin de souligner l'importance de chaque contribution. Basé sur des schémas cinétiques classiques à coeur rétrécissant prenant en compte des diverses contraintes lors d'une réaction non-catalytique de gaz/solide et sur des modèles de combustion homogène pour les gaz, un modèle a été développé pour représenter l'évolution temporelle de la pression d'explosion pour ces mélanges

The explosion sensitivity and severity of various gas/vapor-dust mixtures have been studied thanks to specifically modified apparatuses based on a 20 L sphere and a Hartmann tube. The specificities of gas/dust hybrid mixtures explosions have been highlighted. In fact, even for gas concentrations lower than the lower explosivity limit (LEL), the ignition probability and the explosion severity can be greatly increased, which will notably lead to great changes in the Ex zones determination. For instance, it has been shown that such mixtures can be explosive when both the dust and gas concentrations are below their respective minimum explosive concentration and LEL. Moreover, synergistic effects have been observed and the rate of pressure rise of hybrid mixtures can be greater than those of the pure gases themselves. The origins of these specificities should not be sought in the modification of a single parameter, but could probably be attributed to combined impacts on hydrodynamics (flame propagation), thermal transfer and combustion kinetics. Experiments have been carried out in order to underline the significance of each contribution. Based on classical shrinking core models taking into account the various limitations during a non-catalytic gas/solid reaction and on homogeneous combustion for gases, a model has been developed to represent the time evolution of the explosion pressure for such mixtures
