Abstract:

Cette thèse regroupe des études portant sur la dynamique de relaxation de différents systèmes conservatifs ayant tous une troncature de Galerkin sur les modes de Fourier. On montre que, de façon très générale, ces systèmes relaxent lentement vers l'équilibre thermodynamique avec une thermalisation partielle à petite échelle qui induit une dissipation effective à grande échelle, tout en conservant les invariants globaux. La première partie de ce travail est consacrée à l'étude de la viscosité effective dans l'équation d'Euler incompressible tronquée. L'utilisation des méthodes de Monte-Carlo et

Abstract:

There is an ongoing interest in analyzing the flow characteristics of swimming fish. Biology has resulted in some very efficient motions and formulating these motions is of interest to engineers. One such theory was written by Dr. William Vorus and Dr. Brandon Taravella involving ideal efficiency. It is therefore interesting to test the calculations to see if it is possible to design a motion that can create thrust without necessarily creating vorticity. The computational fluid dynamics software of ANSYS Fluent was used to calculate the resulting flow field of the eel motion to compare with th

Abstract:

The study of shear flow steady states has led to a wealth of research in the field of fluid dynamics. By studying shear flows, we can understand how a fluid behaves and how coherent structures arise. We primarily study the stability of shear flows in the Euler equations. The Euler equations describe the dynamics of an ideal fluid which is incompressible, inviscid, and experiences no external forces. We study the family of shear flows of the Euler equations with vorticity of the form Ω(x,y)=cos(κxpxx+κypyy) on a two-dimensional periodic domain of size [0,2π/κx)×[0,2π/κy), and formulate this as

Abstract:

The study of acoustic radiation force and torque phenomena has attracted an enormous interest of the scientific community, due to applications of these phenomena in noncontact particles manipulation. In this work, we perform a theoretical analysis of acoustic radiation force and torque exerted on a homogeneous visco elastic particle in the Rayleigh scattering limit (the particle radius is much smaller than the incident wavelength) by a wave with arbitrary geometry. Our study is based on the partial-wave expansion in spherical coordinates of the incident and scattered waves

Abstract:

In the arid west, water is among the most valuable of resources. Typically, in order to successfully and accurately measure a flow rate using most types of flow meters, it is recommended that a straight section of pipe be installed immediately upstream from the flow meter to avoid distorted flow patterns and extreme turbulence at the metering location. In many field piping situations, however, such flow conditions are impossible to achieve. The performance of ultrasonic flow meters in non-ideal piping scenarios was studied using laboratory experiments and numerical Computational Fluid Dynamics

Abstract:

In this thesis extensions to the formalism of endoreversible thermodynamics for multi-extensity fluxes and chemical reactions are introduced. These extensions make it possible to model a great variety of systems which could not be investigated with standard endoreversible thermodynamics. Multi-extensity fluxes are important when studying processes with matter fluxes or processes in which volume and entropy are exchanged between subsystems. For including reversible as well as irreversible chemical reaction processes a new type of subsystems is introduced - the so called reactor. It is similar t

Abstract:

An anguilliform swimming robot replicating an idealized motion is a complex marine vehicle necessitating both a theoretical and experimental analysis to completely understand its propulsion characteristics. The ideal anguilliform motion within is theorized to produce ``wakeless'' swimming (Vorus, 2011), a reactive swimming technique that produces thrust by accelerations of the added mass in the vicinity of the body. The net circulation for the unsteady motion is theorized to be eliminated. The robot was designed to replicate the desired, theoretical motion by applying control theory methods. I

Abstract:

<p>In this thesis we study the coherent vortices of a two-dimensional incompressible ideal fluid (the Euler equations) which is important to many physical systems, including the atmosphere of outer planets, two-dimensional turbulence, and pure electron plasma experiments. Using the statistical equilibrium theory derived recently which respects all the infinite conservation laws of the ideal fluid, we solve the coherent vortex solutions in a disk and an annulus. In addition to finding the solutions, we develop the formulation and numerical scheme for a bifurcation and a thermodynamic stability

Abstract:

In this thesis, we consider the non-uniqueness of weak solutions to the compressible isentropic Euler equations on a bounded domain. We establish a criterion for the existence of infinitely many solutions with the same initial data. Using this criterion, we prove that for general smooth initial density and velocity, there exists infinitely many weak solutions. Furthermore, given smooth initial density bounded away from zero, we can construct a initial velocity field such taht there exists infinitely many weak solutions with this initial data, and these solutions satisfy the entropy inequality

Abstract:

The thesis is devoted to the numerical modelling of two- and three-dimensional ideal fluid flows in channels of complicated geometries on the basis of the adaptive grid method. Iterative finite difference methods for the numerical modelling of ideal gas and fluid flows are developed using new dependent variables. For two-dimensional flows these variables are stream function and vorticity function, for three-dimensional flows these variables are: vector potential and vorticity vector. The set of equations for the stream function and vorticity, for which the appropriate boundary conditions are t

Abstract:

The purpose of this research is the development of a method for studying a two-dimensional semi-linear elliptic partial differential equation in an infinite stripe with slow variations of one of the boundaries. The problem is reformulated as a boundary value problem for a semi-linear elliptic equation with a small parameter at one higher derivative (the singular perturbation parameter). The method is based on the boundary function of Tikhonov, shaped by Vasil?eva and Butuzov for a one-dimensional case. The developed method has clear parallels with the one-dimensional boundary function method.

Abstract:

This (Diplom-) thesis deals with the particle trajectories of an incompressible and ideal fluid flow in 𝑛 ≥ 2 dimensions. It presents a complete and detailed proof of the surprising fact that the trajectories of a smooth solution of the incompressible Euler equations are locally analytic in time. In following the approach of P. Serfati, a complex ordinary differential equation (ODE) is investigated which can be seen as a complex extension of a partial differential equation, which is solved by the trajectories. The right hand side of this ODE is in fact given by a singular integral operator whi

This work develops a discontinuous Galerkin finite element discretization of non- linear hyperbolic conservation equations with efficient and robust high order stabilization built on an entropy-based artificial viscosity approximation. The solutions of equations are represented by elementwise polynomials of an arbitrary degree p > 0 which are continuous within each element but discontinuous on the boundaries. The discretization of equations in time is done by means of high order explicit Runge-Kutta methods identified with respective Butcher tableaux. To stabilize a numerical solution in the
