Milieux Divisés et Fluides Complexes


Suspensions et Fluides Complexes

Cette thématique s’intéresse aux écoulements de milieux fluide/grain. Les sujets concernent la rhéologie des suspensions denses macroscopiques ou colloïdales, les milieux granulaires immergés, les suspensions capillaires, le mélange dans les suspensions et les milieux poreux, ainsi que la sédimentation et le transport de particules dans un écoulement. Notre approche associe l’analyse à l’échelle des particules, le développement de rhéomètres originaux et l’étude de configurations d’écoulement proches des situations industrielles ou géophysiques.

Nous avons abordé le problème classique de la rhéologie des suspensions en terme de rhéologie frictionnelle, par analogie avec les milieux granulaires secs. L’idée est d’imposer la pression particulaire, en laissant à la fraction volumique la liberté de s’ajuster aux conditions de l’écoulement. Cette approche permet de sonder le comportement de la suspension proche du jamming, tout en évitant les problèmes de divergence de viscosité rencontrées en rhéométrie conventionnelle. Nous avons développé un tel rhéomètre à “pression imposée” pour caractériser la rhéologie des suspensions denses de sphères dures non-Brownienne, unifiant la rhéologie des granulaires secs et des suspensions denses. Nous étendons depuis cette approche à des suspensions et des situations plus complexes, comme les suspensions de fibres, les suspensions immergées dans des fluides à seuil ou rhéo-épaississants, les suspensions Browniennes, la transition entre le régime visqueux et inertiel, les phénomènes d’hystérésis et nonlocaux. Parallèlement à ces études, nous étudions dans ces systèmes l’apparition de contraintes normales et les phénomènes de migration de particules lorsque le cisaillement n’est pas homogène.

Le rhéo-épaississement a lieu dans les suspensions dont la viscosité augmente, parfois de plusieurs ordres de grandeurs, lorsqu’on leur impose un taux de cisaillement supérieur à une value critique. Les propriétés des suspensions rhéo-épaississantes jouent un rôle crucial dans la formulation des bétons modernes ou la conception d’absorbeur de chocs. Cependant, l’origine physique de ce phénomène est longtemps restée une énigme. Récemment, de nouvelles idées théoriques et travaux numériques ont proposée que le rhéo-épaississement provenait d’une transition frictionnelle, liée à l’existence d’une force de répulsion à l’échelle microscopique entre les grains.  Nous testons ce scénario et ses conséquences sur la rhéologie en utilisant : (1) des suspensions colloïdales modèles dans lesquelles la force de répulsion entre particules peut être contrôlée;  (2) des rhéomètres à pression imposée adaptés aux particules de taille micrométriques, donnant accès au frottement de la suspension. Nous étudions également les écoulements et la stabilité de ces suspensions dans des configurations hydrodynamiques, comme des plans inclinés, des silos ou des conduites.

Many industrial and environmental processes involve the coupling between a particulate suspension and an interfacial flow. These applications often exhibit flow conditions that are difficuly to probe using conventional rheometry, such as elongational flow, transient deformation, confinement and capillary effects. We address these issues using controlled flow configurations and non-colloidal suspensions in order to identify the effect of the different suspension’s parameters (solid fraction, particle diameter, fluid’s viscosity, wettability). Various canonical situations have been considered, such as the impact of solid objects onto a granular suspension, the impact on drops on a solid surface, the pinch-off of capillary bridges, the breakup of jets or the dip-coating of particulate suspensions.

Sheared particulate suspensions constitute a very unique system where efficient mixing spontaneously occurs even under low Reynolds number conditions. The intense dispersion and mixing properties of sheared suspensions arise from the presence of particles which confer to the interstitial fluid a stochastic component. Understanding how mixing proceeds in sheared particulate suspensions has applications for instance to be able to predict the transport of drugs or oxygen in blood flow, the homogenization of adjuvants during concrete preparation or the transport of nutrients inside certain biological cells. In this project, we aim at clarifying the dispersion and mixing of scalar quantities like temperature and concentration molecules that is sheared in a suspension of spherical particles. Measurements of the spatio-temporal local concentration and interstitial flow field are compared to the theoretical predictions inferred from the knowledge of the flow kinematics. We also extend our approach to mixing and transport in other complex media, such as porous materials, reactive species or plant tissues.

Although sedimentation can be considered as one of the simplest examples of suspension flow, much remains unknown about the fundamental properties of sedimenting suspensions. The problem that one encounters lies in the long range nature of the multibody hydrodynamic interactions between particles. The situation becomes even more complicated when inertia is added, when particles become more complex or when they are transported by a flow. We address these issues by studying the sedimentation and transport of particles both at low Reynolds numbers and when inertial effects start to be important. Particles can be spheres or anisotropic objects like fibres, they can be rigid or soft, isolated or in assembly like in clouds of particles. The external fluid can be still or in motion, with temporal and spatial fluctuations. Our approach combine idealized experiments and simple numerical simulations to identify the physical mechanisms and test the different models.

Erosion, sediment transport and submarine avalanches are geophysical phenomena that involve the coupling between a flow (interstitial fluid pressure, external shear stress) and an immersed granular material. We address these situations at the laboratory scale using model particulate systems and fluids. We have studied the onset of sediment transport by a laminar shear flow and the transport law above the threshold, the instability of the sediment layer and dune formation, avalanche triggering and flow of immersed grains. Experimental results are analyzed within two-phase continuum frameworks, in which we incorporate the frictional rheologies identified in the group.

Flow of Complex Fluids

Granular materials and dense suspensions are not the only example of media that exhibit a solid-to-liquid flow transition. Complex fluids such as foams, paste, gels or concentrated emulsion also experience a yield-stress below which they behave like a solid and above which they flow like a liquid. These media are most often studied in rheometers. We have investigated the flow behavior of model yield-stress fluids such as Carbopol gels or clays suspensions in more unusual configurations such as drop impact or horizontal oscillation. These situations reveal the importance of elasticity or thixotropic effects in the unsteady and transient flow response of yield-stress fluid.
