Testo completoThis study aims to highlight the stabilization of nuclear decontamination foam by hydrophilic and hydrophobic mineral particles. Hydrophobic particles consist of homogeneously-grafted colloidal silica, and we have examined their ability to make an ideal gas-liquid interface viscoelastic. Hydrophilic particles are micrometric agglomerates of fumed silica, which turn foaming solutions into thixotropic yield-stress materials. The resulting foams can retain up to 75 % of their initial liquid during several hours. These remarkable drainage kinetics are explained with regards to the confining of agglomerates, studied both in a specifically-developed rigid porous media and in a foam with mobile interfaces and size-controlled bubbles. A percolation threshold appears in the porous media but can not take place in the foam owing to the interfaces deformability. Liquid is retained in the porous agglomerates trapped within the foam channels. The whole results have been patented

Testo completoCrude oil is already usually trapped into heterogeneous porous media. In order to increase the recovery efficiency, one of the chemical solutions consists in injecting foams in porous media to expel oil from the rock. Foam is indeed able in some cases to greatly decrease the mobility, leading to a better sweeping of the reservoir. However, the mechanisms controlling the foam mobility are not well known. We propose a microfluidic approach allowing a direct observation of the flow of bubbles in a model of porous media. We observe that the flow is not homogeneous in the porous medium: it is concentrated in some paths. The number of these preferential paths depends of the foam quality and the capillary number. If we simplify the geometry of the porous medium to a loop, we prove that the formation of preferential paths depends of the size of the loop. Indeed we can only immobilize the bubbles if the size of the loop is around the size of the bubbles

Testo completoIn enhanced oil recovery (EOR), foams are injected in porous media to improve oil recovery efficiency. The objective is to limit viscous fingering thanks to the high effective viscosity of the foam at low capillary number Ca. Foam is produced by the co-injection of a gas and a solution of surfactants. This thesis focuses on foam formation and transport mechanisms in model porous media using a heterogeneous micromodel made in NOA. Foam formation is studied using two different approaches. The first one consists in studying a co-injection of two fluids thanks to a jet flowing in the center of the system. This experiment shows that the less wetting fluids is dispersed in the other one when the capillary number is higher than 10-5. A second set of experiments is conducted by injected a pre-formed train of big bubbles in model a porous media. The bubbles divide until they reach a diameter of the order of to the pore size, for high enough capillary numbers Ca. Besides, we studied the transport properties of foam in similar model porous media. Direct measurements show that the pressure drop induces by the flow can be at Ca=10-6 as high as 3000 times the pressure corresponding to water injected at the same injection flow rate. This ratio decreases with capillary number. An analysis of the preferential paths by direct observations shows that, for low relative gas flow rate, only a few paths are active. However, an increase of the capillary number or if relative gas flow rate leads to a homogenization of the flow in the medium. Thanks to different simple models of straight or wavy channels, we measure that the pressure drop induced by a single bubble is in good agreement with Bretherton’s law, and scales as Ca2/3. However, in wavy channels the pressure drop due to a single bubble deviates from this prediction and exhibits a plateau at Ca lower than 10-4. In this regime, the motion of the bubble is usually intermittent. Finally, we focus on foam formation and transport properties in presence of oil. Our observations lead to the conclusion that for our setup and surfactant formulations, oil has a negligible influence

Testo completoThis thesis aimed at advancing our knowledge of the rheological behavior of foams in porous media. For that, we performed a comprehensive systematic petrophysical study of foam flow in porous media to determine the impact of foam quality, flow rate (interstitial velocity), permeability, pressure and gas composition on foam performance. Our findings show that the data obtained over a range of foam qualities, interstitial velocities and permeabilities converged to a power law master curve, independently of the flow regime, once the rheological behavior of strong foam was expressed in terms of apparent viscosity as a function of shear rate. The master curve obeys a power law with a universal exponent of -2/3. We found experimental and theoretical evidence in the literature for the value of the exponent. Our results also showed that foam was less effective in reducing gas mobility as pressure increased and that at sufficiently low pressures, the gas composition has no effect on foam performance. However, at high pressures, the gas composition becomes a determinant parameter, and all components must be considered. We found a master curve for foam performance which allows us to extrapolate foam efficiency for different compositions at different pressures. The experimental correlations obtained by these original approaches hold immense potential to advance the physical modeling of foam flow in porous media. Therefore, both approaches and correlations above can be used to refine foam flooding modeling, thus improving the simulation of Foam-EOR process and its reliability

Testo completoAmong the various types of existing foams, we investigate the aluminium foam prepared with infiltration technique. In order to improve their mechanical behavior and especially their energy absorption capacity under impact, we introduced various polymers into the pores to engender a new composite Bi-material: Metal Porous Polymer Composite (MPPC). The principal goal of this study consists of the preparation of aluminium foam and composites (MPPC) and the exploitation upon their mechanical properties under load compressive and impact. For this aim and based on a bibliographical study, we designed and installed necessary equipment to prepare the materials. In order to predict and control the porosity of the aluminium foam, a simplified and idealized physical model was established. In consequence, the mechanical behavior of materials was studied with static compression tests. For obtain necessary information to choose the appropriate foam or composite in the real occasion, the influence of the structural parameters on the mechanical response was investigated. Moreover, a numerical simplified model was proposed to establish the relation between the structure of cellule and the elastic module. In the last part, the dynamic properties of foam and composite were studied under point impact. In the same way, we studied the influence of the structural parameters and the conditions of tests on the responses of materials under impact
