Pełny tekst źródłaIn this PhD work, sensitivity studies are carried out for turbulent shear flows using direct noise computations and the complex differentiation method.First, the complex differentiation method is applied to two-dimensional mixing layers to investigate its capacity to highlight the effects of a parameter on the aerodynamic noise.For that, direct numerical simulations of mixing layers are performed using this method for different Mach numbers, Reynolds numbers and mesh spacings.In each case, the derivatives of the noise levels with respect to one of the three parameters are obtained using the complex differentiation method.The results are in good agreement with others from the literature and parametric studies.They indicate that the complex differentiation method can be used to describe the effects of physical parameters and of the grid resolution on the sound produced by a high-speed flow.Secondly, the complex differentiation method is applied to the study of the receptivity mechanism occurring when an acoustic wave reflects at the nozzle lip of a jet.For this purpose, using the results of a simulation of a jet impinging on a plate, an imaginary amplitude acoustic pulse is introduced at a given time in the near-nozzle region outside the jet.The sensitivity of the near-nozzle mixing layers to an acoustic disturbance is then determined using the complex differentiation method.This sensitivity is used to highlight the excitation of an instability wave by the acoustic disturbance.Finally, the influence of nozzle-exit conditions (velocity profile and turbulence level) on the tonal noise components generated by subsonic impinging jets is investigated.For that, jets with different nozzle-exit velocity profiles, several boundary-layer excitation levels, at Mach numbers of 0.6 or 0.9, impinging on a plate located at 6 or 8 nozzle radii from the nozzle, are simulated.The results show that the nozzle-exit conditions significantly affect the amplitude of the tonal noise components and that impinging jets at Mach numbers below 0.65, which are generally non-resonant, can be resonant for specific nozzle-exit conditions.The effects of the nozzle-exit conditions are found to result from changes in the development of the jet mixing layers, which lead to differences in the amplification properties of the Kelvin-Helmholtz instability waves between the nozzle and the plate, and in the energy contained in the coherent structures of the jets near the impingement region

Pełny tekst źródłaIn engineering, for a better understanding of the mechanical behavior of a structure submitted to some perturbation of the modeling parameters, one often proceed to a sensitivity analysis. This provides quantitative and qualitative information on the behavior of the model under study and gives access to gradients that may be used in identification and optimization methods. In this thesis, we demonstrate that this information may be obtained at a low development effort by applying an Automatic Differentiation (AD) tool to the computer code that implements the model. We adapt the AD techniques to the Asymptotic Numerical Method (ANM), in its Diamant version for sensitivity computations of numerical solutions of nonlinear problems discretized through a finite element method. We discuss in a generic manner both the theoretical aspects and the implementation of several algorithms written in Matlab. Applications are concerned with sandwich beams and sandwich plates in both the static and dynamic (free vibration) cases. Sensitivities are computed with respect to geometric and mechanical parameters, and with respect to elementary stiffness matrix. The generality of our developments allows to take into account several viscoelastic laws with no additional effort. Three kinds of viscoelastic models are studied: constant complex modulus, low damping and higher damping. In comparison with the finite difference approximation often used in mechanics, our approach provides more accurate results for the sensitivity of the structure response to a perturbation of the modeling parameters. It also allows a reduction of the computation effort

Pełny tekst źródłaThis work is dedicated to numerical simulation of flow of solid-liquid mixtures. The fluid flow obeys a Newtonian behavior and suspended particles are modeled by rigid spheres or sticks. This suspension is appropriate for composites injection molding. Our goal is to better understand the rheological behavior of such a mixture under a shear flow. So we consider the evolution of this mixture in a cubic cell, under a shear flow, with pseudo-periodic boundary conditions. We extend the velocity-pressure equations to solid domain by adding a rigid constraint. Thus we obtain a system of velocity-pressure equations defined on the whole fictitious domain that we solve by a Finite Element method. In this multidomain approach, we have to follow the evolution of the positions of solid particles. The solid domain is represented by a characteristic function. A lagrangian transport is used to update the positions of particles, and the corresponding characteristic function is deduced at any time thanks to a Level-Set method. A collision algorithm is used after this transport to correct positions and prevent particles from interpenetrating. Homogenization calculus have been done in order to estimate equivalent viscosity for suspensions of spheres, and behavior laws and models for evolution of orientation tensors in suspensions of fibers. Boundary effects are reduced thanks to pseudo-periodic boundary conditions. Moreover the interface description is improved by a h-adaptation technique. Our results are in rather good agreement with theoretical models, and a first simulation of a 3D mixture flow is presented

Pełny tekst źródłaThe adjoint mode of Algorithmic Differentiation (AD) is particularly attractive for computing gradients. However, this mode needs to use the intermediate values of the original simulation in reverse order at a cost that increases with the length of the simulation. AD research looks for strategies to reduce this cost, for instance by taking advantage of the structure of the given program. In this work, we consider on one hand the frequent case of Fixed-Point loops for which several authors have proposed adapted adjoint strategies. Among these strategies, we select the one introduced by B. Christianson. We specify further the selected method and we describe the way we implemented it inside the AD tool Tapenade. Experiments on a medium-size application shows a major reduction of the memory needed to store trajectories. On the other hand, we study checkpointing in the case of MPI parallel programs with point-to-point communications. We propose techniques to apply checkpointing to these programs. We provide proof of correctness of our techniques and we experiment them on representative CFD codes

Pełny tekst źródłaCavitation is a phase change phenomenon, wich occurs in low pressure areas in hydraulic systems. Its consequences are often harmful and undesired : it causes loss of efficiency, noise and vibration generation, and structural abrasion... These effects become a major preoccupation in the conception of hydraulic systems. The main objective of this work is to develop a numerical tool for the numerical modelisation of cavitation at high orders of accuracy, for compressible and viscous flows, in complex geometries. The model used for the modelisation of the cavitation is the homogeneous mixture model, wich formulation is independent of empirical parameters, and is easily extendable for multi-spieces flows. We use a finite volume developped in the DynFluid laboratory, in wich the high accuracy order of reconstruction is obtained using the Moving Least Square approximation

Pełny tekst źródłaTearing of the muscle-tendon complex is a common sport-related injury for athletes. Many studies reported description of this traumatism but mechanisms leading to such an injury are still unclear as are the site of mechanical failure and involved structures. The aim of the thesis is to describe the phenomenon of the muscle-tendon-complex’s tear using the discrete element method and validating the numerical model with experimental data. In the first part, a literature review explains the different properties of the muscle-tendon complex main components’ in order to model it at the macroscopic scale. In the second part, the muscle-tendon complex is modeled. Validation of the mechanical behavior in passive tensile test is proposed by comparison with experimental data from L.-L. Gras on human sternocleidomastodeus muscle. Then, the different influences of morphometric parameters on the mechanical behavior of the complex are investigated. The third part focuses on the rupture. A model of the complex set of {Achilles tendon/surae triceps} is built and a tensile test until rupture is applied. Model validity is assessed by comparison with in vitro experiments from human cadavers. The fourth part focuses on the muscular activation, implemented inside fibers’ behavior. Validity of its active behavior is investigated. This fifth and last presents the enrichment with destructive tensile test. This added test allows first to study the feasibility to model the tear with the discrete element method; and second to focus on damaged structures and rupture’s mechanisms. This offers possibilities for clinical applications of this model to understand and prevent injuries caused by a tear of the muscle-tendon complex
