Ommi, Siddhartha Harsha. « Study of hydro-mechanical instabilities in geomaterials ». Thesis, Ecole centrale de Nantes, 2022. http://www.theses.fr/2022ECDN0017.
Hydraulic and mechanical instabilities in geomaterials refer to a variety of non-linear phenomena that can be triggered by heterogeneities inherent to such materials. While hydraulic instabilities manifest themselves as heterogeneous fluid invasion causing `fingering' phenomenon, mechanical instabilities represent strain localizations and/or fractures. These instabilities and their associated coupling pose a major obstacle for applications involving geomaterials such as Carbon dioxide (CO2) sequestration and contaminant flow in ground waters. Existing classical models lack the required pattern-forming ingredients in their formulation and thus are stable against imposed perturbations. The essence of the current thesis work is to propose and investigate modeling techniques that allow to describe these instabilities. The constitutive approach adopted is that of micro-structured continua, in particular that of enhanced continua with a constitutive law depending on the gradient of so-called phase field variables.In the first part of this work, a fluid-fluid front has been described as a diffused interface by interpreting the presence of two fluids within the pore space as a single non-uniform fluid and the degree of saturation of one of the fluids as the corresponding phase field. While the classical one-to-one relation between capillary pressure and saturation degree describes retention properties of the porous network, an enhanced relation is obtained by prescribing a chemical potential in the spirit of Cahn-Hilliard type modeling of multi-phase fluids. This together with a non-local energy contribution provides the required ingredients required to describe hydraulic instabilites. In a one-dimensional setting, the proposed model allows to replicate experimentally observed non-monotonic saturation profiles during infiltration. Further, a slight non-convexity introduced into the flux function has been shown to allow modeling of drainage fronts, besides imbibition, without employing any additional complexities. A linear stability analysis (LSA) revealing the growth in time of arbitrary perturbations has been done, supplemented by two-dimensional simulations portraying the ability of the proposed model to describe fluid fingering and segregation.In the second part, triggering of a fracture within a drying porous medium has been studied. A prevailing modeling perspective, involving gradient damage modeling, has been first tested for its ability to replicate periodic fracture formation as observed in representative experiments. Further, a new paradigm has been introduced by interpreting the presence of a fracture as a loss of capillary properties, thus allowing passage of non-wetting fluid under vanishing capillary pressure. This is applicable to cohesion-less and unconsolidated fine-grained soils, where resistance against tensile loading is negligible and thus fracturing induced due to development of tensile stresses is not the prevailing phenomenon. Starting from the principles of variational approach, it has been shown that for sufficiently strong desiccation, damage initiates homogeneously on the drying face while progressing into the body with time. The possible occurrence of bifurcations of this base solution, representing initiation of periodic fractures, has been analyzed again in the framework of LSA.This work sets the stage for the study of coupling between the above mentioned instabilities and experimental investigation of unstable flow features such as pinching and coalescence of the wetting phase. Initiation of damage induced due to evolving drainage finger is also of particular interest in the context of earlier mentioned applications
Dupuis, Victor. « Étude expérimentale d’écoulements soumis à une transition longitudinale de rugosité en lit simple et en lit composé ». Thesis, Lyon, 2016. http://www.theses.fr/2016LYSE1154/document.
This PhD thesis investigates the effect of a longitudinal change in floodplain land use on an overflooding river flow. We consider a transition between a meadow and a woodland and vice versa. This change in land use is associated with a change in hydraulic roughness, between a bed roughness (highly submerged meadow) and emergent macro-roughnesses (trees), respectively modelled by a plastic artificial grass and an array of emergent cylinders. The flows are experimentally investigated in an 18 m x 3 m laboratory flume. In a first step, we investigate the flow through a cylinder array in a single channel, focusing on the effect of bed roughness on the cylinder wakes and on the seiche phenomenon (strong free surface oscillations). In a second step, we study the development towards flow uniformity of compound channel flows with a uniform hydraulic roughness on the floodplains. The asymmetrical growth of the compound channel mixing layer, the self-similarity property and the three-dimensional organisation of the turbulent coherent structures associated with the mixing layer are analysed. In a third step, we investigate the longitudinal change in roughness in compound channel configuration, which effects on mixing layer and on coherent structures are discussed. We also assess the contributions to lateral transfers of momentum between main channel and floodplain by turbulent diffusion, by mass exchange and by secondary currents

Carbopol 940 powder is mixed with tape water to form Carbopol slurry that has Bingham-fluid rheological properties. The Carbopol slurry is mixed with glass spheres to form a particle-slurry mixture that still has Bingham-fluid properties. The effects of the size and the content of the glass spheres on the Bingham-fluid parameters such as the Bingham yield stress and the Bingham viscosity are studied in the present study. We use the 4 diameters glass spheres, which were 1mm, 2mm, 5mm, 10mm, respectively. The experiments were mixed uniform and non- uniform particles into the Carbopol slurry. In uniform particles experiments, the four diameters spheres were add into the slurries with different content. The results showed the gravels size and content of Carbopol slurries affects the Bingham-fluid parameters. Bingham yield stress and Bingham viscosity were increased with particle content, and the increments of rheological parameters were significant with small particle diameters. In non- uniform particles experiments, we blend five sets particles with two diameters gravel into the Carbopol slurries, the experimental results show that particle size distribution and content ratio affect the rheological parameters. The increments of Bingham yield stress and Bingham viscosity were decreased while the maximum packing concentrations of Carbopol particle-slurries were increased.
