Full textThis thesis aims at investigating experimentally, analytically and numerically, the consequences of hydrodynamic variations and oscillations with high temporal variability in partially saturated porous media. The problems investigated in this work involve “free surfaces” both outside and inside the porous media, the free surface being defined as the “atmospheric” water pressure isosurface (Pwater = Patm). The laboratory experiments studied in this work are, respectively: Lateral imbibition in a dry sand box with significant capillary effects; Transmission of oscillations of the free surface through a vertical sand box placed in a small wave canal (IMFT, Toulouse); Dynamics of free surface oscillations and wave propagation in a large wave canal (HYDRALAB, Barcelona), partially covered with sand, with measurements of both open water and groundwater levels, and of sand topography (erosion / deposition). For theoretical studies, we have developed linearized analytical solutions. Here is a sample problem that was treated analytically in this work: The linearized equation of Dupuit-Boussinesq (DB) for transient free surface flow, assuming horizontal flow and instantaneous wetting/drainage of the unsaturated zone: forced oscillations, wave transmission and dissipation through a rectangular sandbox. We also developed a weakly nonlinear solution of the Dupuit-Boussinesq equation to study the sudden imbibition (temporal monitoring of the wetting front). We have studied the different types of transient flow problems related to the experiments cited above by numerical simulation. In particular, we have simulated unsaturated or partially saturated transient flows in vertical cross-section, using a computer code (BIGFLOW 3D) which solves a generalized version of Richards’ equation. Thus, using the Richards / BIGFLOW 3D model, we have studied numerically the experiment of unsaturated imbibition in a dry sand (IMFT sandbox), and then, with the same model, we have also studied the partially saturated wave propagation experiment in the large Barcelona wave canal (HYDRALAB laboratory), focusing on the sloping sandy beach, with coupling between the micro-porous zone (sand) and the “macro-porous” zone (open water). To interpret the results of the latter experiment and compare them to simulations, we use several methods of signal analyzis and signal processing, such as: Fourier analysis, discrete multi-resolution wavelets (Daubechies), auto and cross-correlation functions. These methods are combined with pre-filtering methods to estimate trends and residuals (moving averages; discrete wavelet analyses). This signal analyzis has allowed us to interpret and quantify water propagation phenomena through a sandy beach. To sum up, different modeling approaches, combined with model calibration procedures, were applied to transient nonlinear coupled flow problems. These approaches have allowed us to reproduce globally the water content distributions and water level propagation in the different configurations studied in this work

Full textHow to generate currents from water waves? Inspired by nature original way of pumping in the embryonic heart, two wave pumps are studied in the present thesis: the resonance wave pump directly inspired by the Liebau's pump and the waves above a submerged plate pump. The origin of the observed circulation is linked to the wave mass transport term: it corresponds to the amount of mass advected by the waves in the surface layer. The latter is the domain between the crest and the trough of the waves and is a part of the flow that is not always submerged. It is possible to amplify this surface term by resonance and by varying the bathymetry. The latter enables to generate local suction toward the surface layer and leads to mean circulation. The problem is described using a simple potential theory and a dissipative model is proposed to take into account wave dissipation due to friction and wave breaking. The simplified model is compared to experiments and simulations in both cases. It provides a simple framework to predict the pumps behavior: the interesting frequency range and the strength of the flow. It is also a tool for the design of real life applications

Full textThe increase of large ships dimensions shifts their structural natural frequencies towards common wave frequencies, inducing more interactions between the classic seakeeping response and the structural response. Accurate modeling of wavestructure interactions becomes a key issue for architects and classification societies during the design of a ship. In this respect, a new numerical tool for fluidstructure interaction is developed, combining a finite difference RANSE description of the fluid domain with ICARE-SWENSE and an analytic beam model, within a modal approach. Thanks to the use of a simple formulation for the structure part, the tool inherits ICARE-SWENSE tolerance properties with regard to large time steps, while still taking into account hydrodynamic nonlinear effects. Results presented for a flexible barge in diffraction and radiation according to flexible modes validate the first steps of the coupling procedure. Special consideration is given to hydrodynamic non linearities threshold and their impact on the structural response. A first implementation is shown for the resolution of the equation of motion for the elastic degrees of freedom. Parametric studies on ship resistance in both regular and bichromatic waves are included as a stepping stone towards future simulations of ship hydroelasticity in irregular waves

Full textVarious forms of beach profile may be found on the earth surface according to the local hydrodynamic and sedimentologic conditions. Despite numerous field, laboratory and theoretical studies, the physical processes which govern beach morphodynamics are still not well understood. This study investigates the physical modeling well controlled of morphological changes of cross-shore sand beach profiles carried out in the LOMC flume of 10m long. The beach consists of non-cohesive fine, to respect the laws of scale and to obtain experimental beaches subject to wave action or wave-tide combination, in similarity to the beaches observed in nature. For a given wave climate, The concept of equilibrium beach profile is verified on a wide range (1,8 < omega < 5,0) of the Masselink and Short (1993)’s classification. The beach bathymetrics profiles in the three directions and the interaction free surface / beach profile near the surf zone are followed with good resolution using two optical methods. The positions of the accretion and erosion zones, and the corresponding sand volumes are deduced from these profiles. Sedimentary bar formation is clearly demonstrated for steady wave climates. The effect of tide on beach profiles was then considered; a smoothing of the profiles was observed. A particular attention to the initial profile has been drawn, can induce in the case of an initial profile without bar, a stronger erosion of the upper part of the beach and a bar position shifted in the offshore direction. The migration of the bar was clearly established at the variation of the wave steepness. The emergence of multiple-barred profiles and the importance of the wave climate history for beach profiles are exhibited. The study of distribution size particle along the beach has been studied. A segregation of grains in surface and volume has been clearly demonstrated. The segregation mechanisms depend on the pore fluid flowing in a granular layer where grains of different sizes move differently
