Full textThis work is concerned with measuring the velocity of liquids loaded with particles using pulsed ultrasonic waves. The velocity of the particles, considered as representative of the liquid velocity, is estimated from the ultrasonic signal backscattered by the moving particles. This backscattered signal is considered as a response to the excitation initially transmitted periodically through the medium. The backscattered signal during a transmission/reception cycle is range-gated to obtain a set of time-windowed signals each associated with a corresponding depth. The objective of this work consists in elaborating algorithms in order to obtain the velocity profile information. The different used methods can be divided into three main categories, coherent methods, incoherent methods and hybrid methods. The first category presents the advantage of providing velocity information with high spatial and temporal resolution. An improvement in estimating the time delay by a regularized cross-correlation method is proposed and validated on a bentonite flow. This method is based on taking into account the time and space smoothness of the velocity field. The incoherent and hybrid methods are necessary when the flows under consideration have large dimensions and flow velocities. It is shown that it is possible, either to reduce the estimate variance, or to improve the maximal unambiguous velocity without affecting the variance. An algorithm based on the localization of the inter-pulse delay is finally proposed in order to remove the phase ambiguity while minimizing the estimate variance at high velocities

Full textThis thesis is about theoretical study and numerical treatment of some problems raised in incompressible free-surface fluid dynamics. The first part concerns a model called the Green–Naghdi (GN) equations. Similarly to the non linear shallow water system (called also Saint-Venant system), the Green–Naghdi equations is a shallow water approximation of water waves problem. Indeed, GN equation is one order higher in approximation compared to Saint-Venant system. For this reason, it contains all the terms of Saint-Venant system in addition to some non linear third order dispersive terms. In other words, the GN equations is a dispersive perturbation of the Saint-Venant system. The latter system is hyperbolic and fits the general framework developed in the literature for hyperbolic systems. Particularly, it is entropic (in the sense of Lax) and symmertizable. Therefore, we can apply the well-posedness results known for symmetric hyperbolic system. During the first part of this work, we generalize the notion of symmetry to a more general type of equations including the GN system. This lets us to symmetrize the GN equation. Then, we use the suggested symmetric structure to obtain a global existence result for the system with a second order dissipative term by adapting the approach classically used for hyperbolic systems. The second part of this thesis concerns the numerical treatment of the free surface incompressible Navier–Stokes equation with surface tension. We use the level set formulation to represent the fluid free-surface. Thanks to this formulation, the kinematic boundary condition is treated by solving an advection equation satisfied by the level set function. This equation is solved on a computational domain containing the fluid domain over small time subintervals. Each iteration of the algorithm corresponds to the adevction of the fluid domain on a small time subinterval and to solve the time-discretized Navier–Stokes equations only on the fluid domain. The time discretization of the Navier–Stokes equation is done by the characteristic method. Then, the key tool which lets us solve this equation on the fluid domain is the anisotropic mesh adaptation. Indeed, at each iteration the mesh is adapted to the fluid domain such that we get convenient approximation and geometric errors in the vicinity of the fluid domain. This resolution is done using the Uzawa algorithm for a convenient finite element method. The slip boundary conditions are considered by adding a penalization term to the variational formulation associated to the problem
