The sperm whale, Physeter macrocephalus, posses the largest biosonar in nature. Made of multiple oil sac, the sperm whale sonar is tailored to function from the sea surface down to a depth of 2 kilometers, emitting click as loud as 236 dB, and is multipurpose, as it produces clicks for either echolocation or socializing. However, the liquid wax that composes is sonar, made the sperm whales the target of whaling until 1986, when the remaining population was far too small to remain commercially viable, especially with the arrival of similar products from the petrochemical industry. The sperm whale population still faces some human threats, with the ingestion of plastic and collision with boats continuing to take a toll on the sperm whale population. Studying sperm whales thus aport outcomes in multiple fields, in conservation, ethology, as well as in bioacoustics. Understanding the mechanism that rules the sperm whale sonar will help to study those other fields, as it is a key element in the sperm whale life. Aiming for that goal, this thesis analyzed three databases with distinct characteristics, obtaining the trajectory of sperm whale dives. Clicks were also linked with the sperm whale that emitted them over multiple years of recording for the same population. A simulation of propagation wave through the sperm whale head was also developed to better understand the complex mechanism of this sonar. Finally, a coupling method was developed to improve the parameters of the simulation using the recorded clicks from the aforementioned databases

The purpose of this research project was to develop a theoretical model dealing with reflection of acoustic waves over a grating of N rectangular cavities. Thus, the diffracted acoustic fields were determined by adapting the Kobayashi Potential (KP) method to the case of a cavity. Then, this developed model was generalized to the case of parallel rectangular cavities gratings and then extended to the case of non parallel rectangular cavities ones. A study of the coupling was achieved in order to understand the variation in the acoustic interaction between cavities with spacings and frequency. This model was compared with theoretical results obtained from the finite element method (FEM) and experimental results obtained in a semi-anechoic chamber for a single cavity and gratings of parallel and non-parallel rectangular cavities. The validity of the theoretical model is supported by the agreement between the numerical and experimental results observed

A probabilistic model and a variational method are being studied for sparse approximation. The variational method use a L2 data term regularized by a mixed norm. These mixed norms are used to structure the sparsity. The resulted functionals can be minimized by iterative algorithms which convergence is proved. These mixed norms give estimates by "generalized thresholding operators". These operators are then modified to localize them or to introduce more persistence. The probabilistic one uses a model a priori of signals as sparse random series of waveforms, with random coefficients chosen in an union of two orthonormal basis. The pdf of these coefficients involve two levels of randomness : the position in the time-frequency space, and the value. The study of analysis coefficients allows us to estimate the time-frequency maps by classification. The signal is then estimated by an orthogonal projection on these maps, and one obtains a decomposition into two layers and a residual

Marchner, Philippe. "Non-reflecting boundary conditions and domain decomposition methods for industrial flow acoustics". Electronic Thesis or Diss., Université de Lorraine, 2022. http://www.theses.fr/2022LORR0094.
This PhD project is devoted to non-overlapping Schwarz domain decomposition methods for the resolution of high frequency flow acoustics problems of industrial relevance. Time-harmonic solvers are difficult to parallelize due to their high-oscillatory behaviour, and current solvers quickly reach an upper frequency limit dictated by the available computer memory. Non-overlapping Schwarz methods split the domain into subdomains at the continuous level and provide a suitable setting for distributed memory parallelization. The problem is solved iteratively on the interface unknowns, where the keystone for quick convergence relies on appropriate transmission conditions. The first part of this thesis is devoted to the design of transmission operators tailored to convected and heterogeneous time-harmonic wave propagation. To this end we study two non-reflecting boundary techniques that provide local approximations to the Dirichlet-to-Neumann operator. On the one hand, Absorbing Boundary Conditions are designed based on microlocal analysis and pseudodifferential calculus. On the other hand, the convected acoustic stability issue is addressed for Perfectly Matched Layers in convex domains with Lorentz transformation. The second part of this thesis describes how to adapt a generic domain decomposition framework to flow acoustics, and applies the newly designed transmission conditions to simple academic problems. We explain the relation between the non-overlapping Schwarz formulation and an algebraic block LU factorization of the problem. Finally we propose a parallel implementation of the method and show the benefit of the approach for the three-dimensional noise radiation of a high by-pass ratio turbofan engine intake

The Kadomtsev-Petviashvili equations (KP) describe the small amplitude long wave moving mainly in the x-direction in shallow water. As for ti Benjamin-Ono equation (BO), it describes such waves moving inside water. We are interested in these equations seen as equations of Benjamin-BonaMahony type (BBM). Our work is subdivided in three parts. ln the first one, we recall the modelling of the different equations. More particularly, we show that the BBM models are obtained from the fundamental principle of dynamics via an asymptotic analysis. We compare then the solutions of the KP equations, respectively of the BO one, with the solutions of the equations of BBM type. ln the second part, we are interested in sorne qualitative properties of the generalized equations of BBM type. Sorne results of continuation in time of bounds on Sobolev norms, decay in time and unique continuation of the solutions, are established. Finally, we conclude with a numerical study of the solutions of the generalized KP equations in space dimension 3. (n this last part, in collaboration with F. Hamidouche and S. Mefire, we inspect numerically the phenomena of dispersion, blow-up in finite time, solitonic behaviour and transverse instability

We are interested in the mathematical and numerical modeling of wave propagation in underground media. We present two propagation model: (i) a generalization of Zener's model for viscoelastic media, (ii) Biot's model for poroelastic media. For each model we achieve a mathematical analysis, In particular, an existence and uniqueness of solution and an energy decay result. For the numerical resolution we construct a method specific to each model, based on a variational approach, a mixed finite elements approximation in space and a finite difference in time. We prove for each scheme obtained, a result of discrete energy decay which provides a sufficient stability condition. To simulate the waves propagation in unbounded domains, we adapt the perfectly matched layers techniques to viscoelastic and poroelastic waves. Finally, we present various numerical validations of the developed methods

Under the effect of solar radiation and salinity, water in the oceans, rivers and lakes can be stratified at a certain depth by a sudden change in density. The lighter layer lays over the heavier layer. The solitary waves which appear at the interface between these two layers can have an influence on ships travelling in this region and even present a danger for them. They can also damage submerged engineering constructions such as oil platforms and rail and road tunnels lying on the seabed. This thesis is devoted to two systems of equations capable of modelling this kind of waves. These systems are obtained by using two different methods. The propagation as well as the collision between two solitary waves are simulated numerically. Iterative filtering allows a quantitative study of the run up and phase shift generated by these collisions

Ultrasonic cavitation has been induced in liquid column of small dimensions. The bubbles movements has been observed and a video-computer assisted selection has been used for selecting the typical features in relation with the size of the bubbles and the transient phenomena. The theoretical interpretations start from the efficient role of the image source for predicting the positions where little bubbles gather within the liquid column. In this way, the existence of quasi stationary planes perpendicular to the symetry axis of the experimental set-up is established. Starting from a partial analogy between the ultrasonics propagation and the high frequency guided propagation, the general dynamic behaviour of bubbles within the liquid column is interpreted from the rectangular TE22 mode of propagation of metallic wave guides; transient phenomena can then be interpreted; some details related to the excitation of the rectangular TE22 mode from the circular vibration mode of the circular emitting source can only be suggested. However, most of the observed phenomena agree with the consequences of the theoretical following analogy : bubble velocity ↔ magnetic field, pressure force↔ electric field

One of the methods for the numerical simulation of waves propagation in unbounded domains consists in limiting the computational domain either by introducing artificial boundary conditions (ABC's) or by using perfectly matched layers (PML) in this work, we study mathematical properties of models which utilize PML and/or ABC's for electromagnetic and elastic waves

Radio wave propagation in high and very high frequency bands is a major subject of interest; mainly because of the rise of telecommunication and GPS technologies. Although, the effective transmission of these signals highly depends on the medium. There is a part of the neutral atmosphere, named ionosphere and located approximately between 60 and 2,000 km, which impact the wave propagation as it is composed of a partially ionised plasma. It is formed through the photo-ionization of neutral species by the solar UV and EUV spectrum. During my Ph.D., my first achievement was to develop a ray tracing tool to solve the HF and VHF radio wave trajectories in a realistic ionosphere. It is based on numerical development of the Fermat's Principle which allows trajectory modelling. To give more insight information on wave propagation, this tool also integrates some wave parameters such as propagation time, total electron content TEC and absorption. A simple tilted dipole magnetic field is implemented, which allow the ordinary and extraordinary propagation mode modelling. As a first application, I used this ray tracing tool to model a SuperDARN coherent HF radar. These radars are dedicated to the observation and study of the high latitude plasma convection. First, I studied the radio wave propagation in synthetic ionosphere profiles, featuring different types of electron density gradients. I have shown that ionosphere profile with a developed E region implies low altitude refraction for waves with low elevation angles and moderate to high absorption. For ionosphere profile with lower density E region, wave may propagate to higher altitude and form echoes region spanning across the F region, while being less absorbed. While adding horizontal electron density gradient in these ionosphere profiles, I have shown that the echoes region keep the same pattern but are shifted in distance respect to the radar. Then, I used these results to study the wave propagation in a realistic ionosphere featuring complex electron density gradients. As a second application, I studied the magnetic field effect on radio wave propagation by modelling the ordinary and extraordinary propagation modes in the case of a ionosonde. It is an instrument dedicated to the sounding of the local vertical electron density profile below the F region peak. In the case of a parallel propagation with respect to the magnetic field, the ray tracing tool modelled the expected behaviour for both propagation modes, in terms of different altitude of reflection and different propagation speed. While modelling ordinary and extraordinary modes in the case of a SuperDARN radar, I have shown that the magnetic field effect was negligible as the propagation is almost perpendicular respect to the magnetic field.

The present study deals with the development of an acoustical prediction model for optimizing the arrangement of enclosures inside buildings. Our approach is based on a diffusion model, which basic assumption is that the diffusely reflective walls of the enclosure generate an energy diffusion process. The aim of this work is to integrate the mixed specular/diffuse reflection phenomenon at the walls into this model. First of all, attempt is made to find a relation between the diffusion process and the mean free path in the enclosure, in order to obtain an expression of the diffusion constant as a function of the scattering coefficient and the room’s shape. As this approach does not out to be appropriate, we propose to simulate the mixed specular/diffuse reflections by means of an empirical diffusion constant, obtained by adjusting the diffusions-based results with results given by a ray tracing approach. This approach is successful in most cases, except for long rooms with specular reflections. A hybrid model, coupling the diffusion model with the image-source model is then developed; the coupling is realised through the intensities via the scattering coefficient. Last, experimental validations show the good behaviour of the developed models. Particularly, the diffusion/image-source hybrid model allows satisfying predictions, both in terms of sound level and reverberation time (with a short calculation time), which can not be achieved by using the ray tracing method

Electromagnetic Compatibility (EMC) and Radiofrequency (RF) constraints in the automotive industry are particularly stringent and require the implementation of methodologies that cover the entire project’s development throughout the design phase. In order to predict the installed performance of products in their operational environment, we developed actions that cover the coupling risks between components and their surroundings, these couplings having an impact on both EMC and functional aspects of RF systems. The main difficulty in designing RF equipments is that the specification, which means the final requirement, is described in relation to the whole vehicle. But during the development phase of a new product, the vehicle is often unavailable, or practically doesn’t exist yet. Furthermore, accelerating the development of vehicles allows less to wait for the final implementation, to be able to tune the product to its environment. A reason that pushes us to develop tools adapted to those needs. This thesis proposes a simulation methodology to predict the behavior of RF receivers taking into account their operational environment. The first chapter is devoted to a panel drawing up the generalities of antennas, the state of the art in system integration and a brief description of numerical methods. Then, the second chapter is devoted to the "detuning" phenomena, where we list, through an experimental approach, the parameters causing the detuning of an antenna. In order to obtain a predictive tool, we model the equipment using a circuit approach, to better quantify these parameters and to propose design rules in the early phases of projects development. Finally, the third chapter is devoted to the radiation analysis. It plans to expand the use of numerical simulation to predict the radiation patterns of RF devices. In this context, we propose a simplified model of an antenna that can be easily integrated at vehicle level

Those two last decades, both in the industrial and academics fields, the needs in numerical simulation of multi-fluid flows involving viscous fluids have strongly increased. This thesis presents a study performed in the frame of a "CNRS/SME" granted Ph-D which major input is the development of an high order interface tracking method based on the Volume Of Fluid concept (V. O. F) and it integration in an industrial CFD code in order to improve it's capabilities in numerical simulation of multifluid flows. This original interface tracking method called SL-VOF (Segment Lagrangian - Volume Of Fluid) uses a piecewise linear interface representation and a lagrangian advection scheme. Various versions of this method arc first tested on simple kinematics cases from which the last version appears to be of fully second order. The two first versions of the method arc then tested throughout 2DV numerical simulations of solitary wave breaking due to a spatial mean water level decrease, slow (beach case) or quick (artificial reef, dike). Two kind of comparisons are then considered:From the initial condition to the breaking point, the characteristics (celerity, crest height, free surface shape) of the wave simulated without the air-water effect are successfully compared with those of the wave simulated with a high order B. L. E. M method. After the breaking point, the air-water interaction throughout the interface is considered with respect to the real density ratio and good comparisons for the interface shape evolution until the splash-up phenomena with experiments conducted in the frame of this study achieve the validation of our method. The beginning of the run-up is although computed. High CPU time have motivated the development of a coupling algorithm with a B. I. E. M. . An application of the coupling to the solitary wave breaking on a sloping beach have shown a computational time divided by a ratio of seven. Moreover, these faster computations compare satisfactorily with experimental data on the wave height

This work is dedicated to the study of the diffraction of acoustic waves by a set of small inclusions, as well as to the development of numerical methods for the simulation of such phenomenons. The main novelty of this work is that we deal with time-domain waves.The first part of this manuscript deals with the asymptotic analysis of the diffraction problem, which is carried out by matched asymptotics, the small parameter being the characteristic size of the defects ε. This furnishes an asymptotic expansion of the acoustic field as a perturbation of the defect-free problem. We prove a consistency result between the total field and its ε-asymptotic expansion.In the second part, using the results of the asymptotic analysis, we introduce two approximate models for the diffraction problem. These models are well-posed and their solution are precise approximations of the total acoustic field. One of the main features of these approximate models is that they both lie on a wave equation in the surrounding medium (without defects), coupled to auxiliary source terms which account for the presence of the inclusions. It is then possible to discretize these approximate models using a finite element method, leading to a numerical method which performs as fast as in the defect-free case, since the underlying wave operator is independent of the defects. We present several numerical results which validate both approximate models as well as some insights about numerical error analysis
