Resumen
The microstructure and stability of aerated whey protein gels were determined. Foamed whey protein gels were obtained using a novel method applying a simultaneous gelation and aeration process. Whey protein gels were produced at different protein concentrations and pH by calcium ion induction at ambient temperature. Two concentrations of calcium ions were used: 20 and 30mM to produce foamed gels with different microstructure. Foamed gels obtained at 30mM Ca<sup>2+</sup> were composed of thick strands and irregular, large air bubbles. For these gels, larger synaeresis and bubble size reduction were observed. Fine-stranded, small bubble size aerated gels obtained at 20mM Ca<sup>2+</sup> were very stable during storage. Decreased protein concentration and increased pH of the gels resulted in an increased bubble size. &nbsp;

Resumen
Dans l’industrie nucléaire, la simulation de transitoires accidentels à l’échelle d’un réacteur devient une composante d’importance croissante de la démonstration de sûreté à destination des agences de surveillance nationales. Elle permet ainsi de limiter le recours à des expériences complexes et coûteuses tout en facilitant l’évaluation des stratégies de mitigation. Cependant, les modèles mis en jeu sont inévitablement volumineux et construits avec une finesse de modélisation rendant difficile la prise en compte de détails géométriques locaux pourtant susceptibles d’influencer significativement la solution globale. Dans ce travail de thèse, on propose ainsi des approches multi-modèles pour l’intégration de tels détails dans un modèle global sans modification du maillage initial (on parle aussi de zoom numérique). Des techniques sont proposées aussi bien pour les structures que pour les fluides, avec un souci de démontrer la précision et la stabilité de la solution multi-modèles couplée comparée à une solution de référence à une seule échelle. Ce travail intègre deux spécificités propres, à savoir son adéquation avec les contraintes de la dynamique rapide avec intégration temporelle explicite et l’objectif de traiter simultanément la superposition de modèles et l’interaction fluide-structure
In nuclear industry, simulating accidental transient sequences at full reactor scale is becoming an increasingly important feature of the safety demonstration towards national agencies. It thus allows limiting the number of complex and costly experiments, while simplifying and accelerating the evaluation of mitigation strategies. However, the implemented numerical models are inevitably heavy to build and maintain, with a global modelling scale making it difficult to account for local geometric details yet able to significantly influence the physical solution. To provide an answer to these problems, this PhD work is dedicated to multi-model approaches designed to integrate such details into bigger models with no modification at the global level (techniques often designated as numerical zoom techniques). Some methods are proposed for both structures and fluids, with special care given to the accuracy and stability of the coupled multi-scale solution compared to a single-scale reference solution. This work handles two very specific topics, namely its compatibility with numerical features imposed by fast transient dynamics with explicit time integration, and the general objective of simultaneously dealing with superimposed models and fluid-structure interaction

Resumen
L'objectif principal de cette thèse est la formulation des mélanges stables contenant l'hydroxyapatite gel synthétisée (Ca-HAGel). Le comportement rhéologique des mélanges Eau/(sulfate de calcium) et hydroxyapatite/(sulfate de calcium) a été étudié. Les résultats ont montré que tout les mélanges sont caractérisés par un comportement rhéologique rhefluidifiant et thixotrope. Le potentiel zeta a été utilisé dans cette étude pour mieux appréhender les interactions entre les particules et leur effet sur le comportement des mélanges. La fixation de sulfate sur la surface de Ca- HA favorise la stabilité de la structure du Ca-HAGel. Les analyses de caractérisation effectuées sur les formulations ont montré la formation de nouveaux composés tels que le sulfate-phosphate de calcium hydrate et l'Ardealite. Les tests de lixiviation et de percolation ont révélé que le taux de relargage de soufre et strontium à partir des sous-produits de gypse était négligeable pour les mélanges contenant Ca-HAGel. Ca- HAGel stabilise les métaux lourds relargués à partir du gypse et plâtre. Les particules du gypse améliorent les performances hydrauliques de Ca-HAGel et le plâtre hydraté stabilise la structure de Ca-HAGel par la formation des particules agglomérées. Le test colonne effectué sur la formulation AWPG2 a montré une grande performance à retenir le plomb et le cadmium avec des capacités de rétention de plus de 99% et 88% respectivement. Le traitement des métaux lourds était lié aux particules de Ca-HA et aux phosphate et calcium libres. La formulation AWPG2 peut être utilisée dans les barrières perméables réactives pour traiter les eaux souterraines contaminées.

Texto completo
Resumen
Shell structure is widely used in engineering area. The purpose of this dissertation is to show the behavior of a thin shell under external load, especially for long cylindrical shell under compressive load, I analyzed not only for linear elastic problem and also for buckling problem, and by using finite element analysis it shows that the imperfection of a cylinder could affect the critical load which means the buckling capability of this cylinder. For linear elastic problem, I compared the theoretical results with the results got from Straus7 and Abaqus, and the results are really close. For the buckling problem I did the same: compared the theoretical and Abaqus results, the error is less than 1%, but in reality, it’s not possible to reach the theoretical buckling capability due to the imperfection of the cylinder, so I put different imperfection for the cylinder in Abaqus, and found out that with the increasing of the percentage of imperfection, the buckling capability decreases, for example 10% imperfection could decrease 40% of the buckling capability, and the outcome meet the buckling behavior in reality.

Texto completo
Resumen
This thesis examines the structure, stability and interaction of geophysical vortices. We do so by restricting our attention to relative vortex equilibria, or states which appear stationary in a co-rotating frame of reference. We approach the problem from three different perspectives, namely by first studying the single-vortex, quasi-geostrophic shallow-water problem, next by generalising it to an (asymmetric) two-vortex problem, and finally by re-visiting the single-vortex problem, making use of the more realistic, although more complicated, shallow-water model. We find that in all of the systems studied, small vortices (compared to the Rossby deformation length) are more likely to be unstable than large ones. For the single-vortex problem, this means that large vortices can sustain much greater deformations before destabilising than small vortices, and for the two-vortex problem this means that vortices are able to come closer together before destabilising. Additionally, we find that for large vortices, the degree of asymmetry of a vortex pair does not affect its stability, although it does affect the underlying steady state into which an unstable state transitions. Lastly, by carefully defining the "equivalence" between cyclones and anticyclones which appear in the shallow-water system, we find that cyclones are more stable than anticyclones. This is contrary to what is generally reported in the literature.

Texto completo
Resumen
An updated stability analysis was performed on the Old River Low Sill Structure due to a change in the operating conditions from historic river sedimentation. Sedimentation of the Mississippi River channel since the 1973 spring flood has caused higher river stages at lower discharges. Numerical methods used included nonlinear analysis of pile group stability, seepage analyses, and limit equilibrium methods. The structure’s foundation was compromised during the 1973 flood, and emergency repairs were conducted to prevent scouring and undermining of the foundation by the flood scour. Rehabilitation included the reconstruction of a failed wing wall on the left abutment, rock and riprap fill in the forebay channel, and emergency grouting to fill the scour hole beneath the structure. An operating restriction was emplaced to limit the differential head across the structure due to flood damage. Taking these conditions into account, results from an updated analysis showed that full headwater uplift caused increased tension in the piles, while the increased body load caused increased compressive loads in the piles. Review of piezometric monitoring and the seepage analyses showed that full headwater uplift is unlikely, indicating the foundation grouting adequately sealed the scour hole beneath the structure. Analysis results exhibited lower magnitude compression and tension loads in the piles with design load cases compared to previous analyses. Recommendations from these analyses indicate that increased monitoring and additional investigation may support increasing the differential head limitation.
