Full textCollective dynamics can be observed among many animal species, and have given rise in the last decades to an active and interdisciplinary field of study. Such behaviors are usually modeled by active matter, in which each individual is self-driven and tends to align its velocity with that of its neighbors.In a classical model introduced by Vicsek & al., as well as in numerous related active matter models, a phase transition between chaotic behavior at high temperature and global order at low temperature can be observed. Even though ample evidence of these phase transitions has been obtained for collective dynamics, from a mathematical standpoint, such active systems are not fully understood yet. Some progress has been achieved in the recent years under an assumption of mean-field interactions, however to this day, few rigorous results have been obtained for models involving purely local interactions.In this manuscript, we describe a lattice active particle system interacting locally to align their velocities. This thesis aims at rigorously obtaining, using the formalism developed for hydrodynamic limits of lattice gases, the scaling limit of this out-of-equilibrium system, for which numerous technical and theoretical difficulties arise

Full textBesides its interest as an industrial application in various processes, liquid fluidization builds up an interesting test case regarding the validation of two-phase flow modelling. The lack of reliable and detailed experimental data about particle agitation in this type of flow is one important motivation to this study. In this work, the random motion of mono-dispersed particles in a liquid fluidized bed has been measured and processed from video recordings, using a refractive index matching method. 3-D trajectories of coloured particles have been collected in a wide range of solid fraction, and statistical quantities have been derived in the range of high particle Reynolds number (O(10)

Full textVesicles are a model system for understanding the dynamical behavior of a closed soft particle such as red blood cells (RBCs) in flows. The inextensible lipid bilayer membrane of a vesicle admits resistance to the bending elasticity, and its large surface-area-to-volume ratio allows the vesicle to exhibit remarkable shape changes in the dynamics even in a simple flow. Significant progress has been made over the past decades in understanding vesicle dynamics in unbounded Stokes flows. This manuscript deals with the numerical investigation of shape transition and lateral migration of 3D vesicles in wall-bounded Stokes flows by means of an isogeometric finite-element method (FEM) and boundary-element method (BEM). Starting from a previously reported isogeometric FEM-BEM simulations of the dynamics of soft particles (drops, capsule, and vesicle) in Stokes flows in free space, the original code is developed to account for microchannel walls of arbitrary cross-section. The present work focuses on the dynamics of a vesicle that is transported through a circular tube in a pressure-driven flow. First, we investigate typical vesicle shapes, different lateral migration modes, and flow structure onto vesicle membrane versus three independent dimensionless parameters, namely, the reduced volume, the confinement, and the (bending) capillary number. Shape transitions and the phase diagram of stable shapes for several reduced volumes are obtained in the (confinement, capillary number) space, showing an extension of the set of vesicle morphologies and rich vesicle dynamics owing to the intricate interplay among the tube wall, hydrodynamic stresses, and membrane bending. Secondly, we study, via an axisymmetric BEM, the hydrodynamics under high confinements in which the shape of the vesicle is expected to maintain axisymmetry. A particular emphasis is given to the prediction of the vesicle mobility and the extra pressure drop caused due to the presence of the vesicle, the latter having implications in the rheology of a dilute suspension. In addition, based on the numerical results of limiting behavior of quantities of interest near maximal confinement, we give various scaling laws to infer, for example, the vesicle velocity, its length, and the thickness of lubrication film. Finally, we present a coupled, hybrid continuum–coarse-grained model for the study of RBCs in fluid flows. This model is based on a combination of the vesicle model with a network of springs with fixed connectivity, representing the cytoskeleton. Numerical results show that this two-component vesicle–cytoskeleton model isable to extract the mechanical properties of RBCs and predict its dynamics in fluid flows

Full textFlow sensing is used by a vast number of animals in various ecological contexts, from preypredator interactions to mate selection, and orientation to flow itself. Among these animals, crickets use hundreds of filiform hairs on two cerci as an early warning system to detect remote potential predators. Over the years, the cricket hairs have been described as the most sensitive sensor in the animal kingdom. The energy necessary for the emission of an action potential by its sensory neuron was estimated to be a tenth of the energy of a photon. This PhD thesis aims to describe recent technological advances in the measurement and model of flows around biological and artificial flow sensors in the context of organismal sensory ecology. The study and understanding of the performance of sensory systems requires a high spatial precision of non-intrusive measurement methods. Thus, non-contacting measurement methods such as and Particle Image Velocimetry (PIV), originally developed by aerodynamics and fluid mechanics engineers, have been used to measure flows of biological relevance. The viscous oscillatory boundary layer surrounding filiform hairs has been visualized and used as input to model the mechanical response of these hairs, described as second order mechanical systems. The viscous hydrodynamic coupling occurring within hair canopy was also characterized using PIV measurements on biomimetic micro-electro-mechanical systems (MEMS) hairs, mimicking biological ones. Using PIV, we have also measured the air flow upstream of hunting spiders. We prove that this flow is highly conspicuous aerodynamically, due to substantial air displacement detectable up to several centimeters in front of the running predator. This disturbance of upstream air flows were also assessed by computational fluid dynamics (CFD) with the finite elements method (FEM). The development of non-intrusive measurement and CFD methods and their application to the analysis of the biological flow involved in cricket sensory ecology allowed us to revisit the extreme sensitivity of cricket filiform hairs. We predicted strong hydrodynamic coupling within natural hair canopies and we addressed why hairs are packed together at such high densities, particularly given the exquisite sensitivity of a single hair. We also proposed a new model of hair deflection during the arrival of a predator, by taking into account both the initial and long-term aspects of the flow pattern produced by a lunging predator. We conclude that the length heterogeneity of the hair canopy mirrors the flow complexity of an entire attack, from launch to grasp
