Full textErosion occurs when a fluid flowing over a granular bed exerts a large enough shear stress. When the fluid encounters an obstacle, the modification of the flow leads to a local over speed, and thus on an increase of the shear stress in the vicinity of the obstacle. As a result, the erosion is locally enhanced and is called scouring. In this work, we investigate this complicated situation experimentally at the laboratory scale. In particular, we address the question of the scouring threshold, i.e., the minimum critical approach velocity of the fluid leading to erosion in the vicinity of the obstacle. We report the existence of two different scouring patterns: the traditional horseshoe scour at the base of the obstacle, which dominates at large flow velocities, and we also highlight another scouring pattern downstream, which is called rabbit ear scour, at moderate speeds. We determine the onset of both erosion patterns visually using different grains and obstacles. Besides, we measure the bed topography over time using a laser profilometer. By monitoring the bed topography during the scouring process, we characterize the morphology of both scouring patterns and rationalize their competitive dynamics by measuring their formation timescale. In most cases, the rabbit ear scour development is inhibited by the faster horseshoe scour growth. The characterization of the flow using Particles Image Velocimetry (PIV), provides information on the shear stress exerted by the fluid flow on the grains, with and without obstacle. We can thus rationalize the threshold values for both scouring patterns, associated with different flow structures

Full textIn many industrials applications, mechanisms such as turbines or pumps function under sever operating conditions: high speed of rotation, high pressures and high Reynolds number. The dynamic behavior of the shaft strongly depends on shaft surroundings elements like journal bearing or annular seals. Many studies use numerical simulations to recreate real operating conditions, but it is necessary to compare theses results with those coming from an experimental test facility. That is why the LMS and its industrial partnerrs (ALSTOM, EDF, CNES, SNECMA) decided ten years ago to design a specific test apparatus for studying annular seals. The functioning of the machine is completely described in this document. In parallel with the project, the behavior law of a thin-walled orifice is studied; the both numerical and numerical studies give the same result for the discharge coefficient. It does not, in this case, correspond to the value from literature. Finally, the last part of the research deals with the development of a specific method to identify the dynamic force coefficients characterizing the behavior of a seal. Many methods use Fourier transformations to work in frequency domain, whereas this methods stay in time domain. Numerical simulations were carried out, but even if the noise is high, results are good. The algorithm is robust, and the main parameters are identified

Full textThis PhD work concerns various means of approaching the flow inside a module of absorber, basic element of a solar receiver, in order to improve his characteristics. Indeed, the development of pressurized receivers dedicated to very high temperature gas cycles would allow the construction of economic thermodynamic solar power plants, with a high efficiency and weak water requirements. A first approach, founded on the use of simulation tools (correlations and three-dimensional simulations) made it possible to define a reference module of absorber, with a basic but functional internal geometry. Then, this module was tested in real conditions. In a second time, investigations were carried out on an optimized internal geometry, based on the development and the use of a textured surface made up of riblets and actuators. A preliminary study of this association in a boundary layer wind tunnel founded on the use of optical metrology lets predict an interesting ratio between the heat transfer coefficient and the pressure losses for the real module of absorber. In order to supplement this preliminary work and to confirm this diagnose, a plate channel wind tunnel, whose geometry is close to that of a real absorber and that allows the measurement of pressure losses, was conceived. The instrumentation (S-PIV diagnoses) of the measuring cell of this wind tunnel made it possible to conclude the characterization of the studied flow

Full textSolute mixing in porous media flows plays a central role in driving chemical reactions in a number of subsurface applications, including contaminant transport and remediation, subsurface energy storage and extraction, and CO2 sequestration. We study the mechanisms of solute mixing, in particular how the pore scale flow topology is related to the mixing dynamics of conservative solutes, with a particular emphasis on the possible emergence of chaotic mixing processes in three-dimensional (3D) porous media. To do so, we perform numerical computations or experimental measurements of the flow velocities and temporal evolution of the concentration fields, and characterize fluid deformation and mixing at the pore scale. This PhD work consists of three main studies. In the first study, we experimentally characterize mixing in a fluid flowing through a two-dimensional (2D) porous medium built by lithography. We measure the velocity distributions from Particle Tracking Velocimetry (PTV). The time evolution of the separation distance between two particles is analyzed to characterize the Lagrangian deformation dynamics. In parallel we perform conservative transport experiments with the same porous media, and quantify the temporal evolution of the mean concentration gradient, which is a measure of the mixing rate. From these experimental results we obtain the first experimental pore scale validation of the lamella mixing theory, which relates the fluid deformation properties to the mixing dynamics. In the second study, we investigate the conditions of emergence of chaotic mixing in the flow through 3D ordered granular porous media. In these periodic cubic crystalline packings (Simple Cubic - SC - and Body-Centered Cubic - BCC) of spheres, we are able to perform highly resolved computations of the 3D Stokes flow. Using custom-developed numerical tools to measure the Lagrangian deformation from the computed velocity fields, we uncover the existence of a rich array of Lagrangian deformation dynamics in these 3D media, depending on the flow orientation. When the flow direction is not normal to one of the reflection symmetry planes of the crystalline lattice, we find that the Lagrangian deformation dynamics follow an exponential law, which indicates chaotic advection. This chaotic behavior is controlled by a mechanism akin to the baker's transformation: fluid particles traveling around a solid grain along different paths end up either separated by, or on the same side of, a virtual surface projecting from the grain surface and called a manifold. Multiple such manifolds exist within the flow, and the way they intersect controls the nature of mixing (that is, either non-chaotic or chaotic), and the strength of chaos. We show in particular that the magnitude of the Lyapunov exponent (a measure of the vigor of chaos) is controlled by the spatial frequency of transverse connections between the manifolds (called heteroclinic intersections). We thus demonstrate that the conventional 2D picture of the mechanisms of mixing may not be adapted for natural porous media because that picture imposes topological constraints which cannot account for these important 3D mechanisms. The third study has two objectives: (i) provide experimental evidence of the chaotic nature of pore scale advection/mixing, both by visualizing the manifolds and by obtaining a quantitative estimate of the Lyapunov exponent; and (ii) assess if the results obtained numerically in ordered packings of spheres extend to random packings, which are closer to natural porous media. The experiment features a random packing of glass beads rendered transparent by optical index-matching between the fluid and solid grains. We use Laser Induced Fluorescence (LIF) to detect the manifolds, and PTV techniques to measure flow velocities and subsequently quantify Lyapunov exponent. The first experimental results are promising
