Full textThis thesis focuses on the study of the dynamics of a thin liquid film subject to an excitation normal to its interface. This situation gives rise to so-called Faraday instabilities that, under certain conditions, lead to the formation of droplets. In the context of assisted injection systems used in aerospace propulsion, there are situations in which the gas stream is not fast enough to effectively peel the fuel film. In this case, Faraday instabilities can produce droplets promoting effective combustion. In this thesis, we are interested in three configurations: first conventional configuration of Faraday : a liquid in a container vibrating without liquid flow and without aerodynamic shear. Then, we focused on a thin film flowing down an inclined plane but always without aerodynamic shear and finally, a thin film flowing down an inclined plane, this time in the presence of an aerodynamic shear. These three configurations were studied through three tools : linear stability, direct numerical simulation with interface capture and experimental approach. For each configuration, satisfactory comparisons between the three different tools have been performed

Full textWhile it is well known that the phenomenon of Faraday instability is a manifestation of vibrational acceleration, its behaviour when both the capillary and gravitational effects vanish, remains unexplored theoretically and experimentally. A detailed experimental and theoretical study is performed to understand the physics of this phenomenon in small rectangular geometry where the proximity of wall results in considerable sidewall stresses. A novel binary liquids system is utilized with low interfacial tension for a near flat interface. Thermal control of fluid system is utilized for achieving reduction in capillary force with study of miscible fluids where interfacial tension reduces to almost zero. In order to discriminate between gravity and capillarity effects, experiments were performed in parabolic flight campaigns. . For the theoretical approach a linear stability analysis is performed through Navier-Stokes equations in a Newtonian incompressible viscous fluid system. This is achieved through a Fourier Floquet method resulting into an eigenvalue problem. Equations are solved by including viscous damping effects for compensating sidewall stresses. Experimentally binary fluids provided a convenient option of changing the coefficient of interfacial tension by temperature control and going through immiscible to miscible system without change of liquid charge. Viscous damping rate is determined experimentally by measuring the linear damping rate. The correction in the theoretical calculations with the viscous damping rate helped in achieving a better understanding of the prediction of the experimental critical amplitude for sub-harmonic and harmonic modes

Full textMixing by vertical vibrations is a growing subject of study thanks to the development of a mechanism by mechanical resonance allowing the mixing of viscous fluids and powders, called RAM (Resonant Acoustic Mixing), and involving Faraday instability. . This thesis is part of the analysis of vibrational mixing by studying the behavior of a two-phase medium, a single-phase fluid containing a concentration of species or a suspension, subjected to this instability. Using numerical simulations carried out with the NOTUS code, developed in the I2M laboratory, comparisons are made between these results and those obtained from the linear analysis of the Faraday instability, as well as experimental data provided by the company Roxel which supports this project. A model allowing to calculate the evolution of the volume fraction during the mixing is implemented in the code in order to be able to simulate the behavior of a loaded fluid subjected to the vibrations imposed by the RAM mixer

Full textWe consider in this thesis the stability problem of a spherical drop subjected to a radial bulk force for two different configurations consisting of an oscillating (with or without a constant component) and a constant force. To do so, we use a full three-dimensional parallel front-tracking code for incompressible multiphase flow to calculate the interface motion. The first configuration consist to the spherical analogue of the Faraday instability. We linearize the governing equations about the state of rest and decompose deformations of the interface as spherical harmonics. Generalizing the Kumar & Tuckerman (1994) Floquet procedure to a spherical interface, we present a linear stability analysis for the appearance of standing waves. The most unstable spherical mode at onset predicted by the linear theory agrees with full three-dimensional nonlinear numerical simulations. The second configuration consists to the spherical analogue of the Rayleigh-Taylor instability when the force is oriented from the heavier to the lighter fluid. We performed numerical simulations for both high and low spherical modenumbers and followed their evolutions up to the nonlinear stage. Finally, we consider a plane interface subjected to an horizontal oscillatory forcing which is called the oscillatory Kelvin-Helmholtz instability. We consider the experimental configuration proposed by Yoshikawa and Wesfreid (2011b) for stably stratified fluids with a high viscosity contrast. Numerical simulations reproduce succesfully the growth and the evolution of the interface. We distinguish a new regime for the interface saturation which was not observed by the original experiment. We obtained a subcritical transition between the two different regimes

Full textThis work presents new aspects of the analogy between time and space in wave phenomena, through new concepts of time control of wave propagation which can be interpreted as the transposition onto the time domain of standard spatial operations. The depth of this analogy is thoroughly studied in the framework of two well-known wave phenomena: reflection of waves on a mirror and their transformation by a crystal. More precisely, we experimentally demonstrate that the time analog of reflection by a mirror generates a time reverse wave that is whose time evolution is inverted. A monofrequency variant of this instantaneous time mirror, which has strong connections to the concept of wave phase conjugation used for time reversing monochromatic waves in optics, is also studied. We show that the periodic time modulation of the medium involved in the latter experiments constitutes the time equivalent of a crystal for waves and we study the general properties of waves in such media. We address of course the issue of the limits of theses space time analogies, of which, the principle of causality is evidently a major constituent. The phenomena studied here are general and apply to all classical waves (usually governed by d’Alembert’s equation or by similar ones). Waves at the surface of a liquid are used as a model wave system in our experiments
Die Universalitat der klassischen Wellenphanomenen lasst sich weitgehend durch die d’Alembertsche Struktur der Wellengleichungen beschreiben. In letzterer spielen die Zeit- und Raumvariabeln eine ahnliche Rolle. Wir betrachten in diesem Werk diese bekannte Analogie unter einem neuen Licht, indem wir neue Konzepte der Zeitkontrolle von der Wellenpropagation introduzieren, die als Transposition zum Bereich der Zeit von standarden Wellenphanomen des Raumes interpretiert werden konnen, wobei die raumliche Variation der Eigenschaften des Mediums, die sie bestimmen, durch eine zeitliche ersetzt wird. Wir bringen den experimentellen Beweis der Relevanz dieses Ansatzes, wobei wir die Wellen an der Oberflache einer Flussigkeit als Modelwellensystem verwenden und zeigen durch theoretische Erkenntnisse, dass er auf alle Wellensysteme generalisiert werden kann, die durch eine Wellengleichung beschrieben wird, deren 10 Struktur die der d’Alembertschen Gleichung ahnelt. Die ganze Reichweite dieser Analogie wird im Rahmen zweier langst bekannten Wellenphanomenen (in deren raumlichen Version), von denen wir zeigen, dass sie eng verbunden sind : die Spiegelung einer Welle und deren Umwandlung durch einen Kristal. Das Equivalent eines Spiegels fuhrt zur augenblicklichen Erscheinung aus dem gesammten Raum einer zeitumgekehrten Welle, das heist einer Wellenform, derer zeitliche Entwicklung im Vergleich zu der originellen Welle umgekehrt ist. Eine Einzelfrequenzvariante dieses augenblicklichen Zeitspiegels wird auch vorgestellt, die enge Verbindungen mit dem fur die Zeitumkehr monochromatischer Wellen angewendeten Konzept der optischen "Phase Conjugation" (Phasenkonjugierung) besitzt. Wir zeigen, dass die dazugehorige periodische Zeitmodulation des Mediums das zeitliche Equivalent eines Kristals fur die Welle bildet, und wir studieren die generellen Eigenschaften der Wellen in solchen Medien. Wir versuchen, die Grenzen dieser raumzeitlichen Analogien zu erkundigen, in derer Bestimmung selbstverstandlich das Kausalitatsprinzip eine masgebliche Rolle spielt, und die interessanten Unterschiede zwischen den vorgestellten Konzepten und deren raumlichen Pendants offenbaren
La universalidad de los fenomenos ondulatorios clasicos es ampliamente descrita por la estructura de la ecuacion de d’Alembert. En esta ecuacion, las variables espaciales y temporales desempenan un papel similar. En esa obra, revisitamos esta analogia bien conocida a traves de nuevos conceptos de control temporal de la propagacion de las ondas, quienes pueden ser interpretados como transposiciones de fenomenos espaciales estandartes al ambito temporal, en los cuales las variaciones espaciales de las propiedades del medio son reemplazadas por las correspondientes variaciones temporales. Hacemos la prueba, usando ondas a la superficie de un liquido, de la relevancia de este enfoque y mostramos teoreticamente su generalizacion a todo tipo de onda clasica, es decir gobernada por una ecuacion cuya estructura es similar a la de d’Alembert. Toda la extension de esta analogia queda estudiada en el cuadro de los dos fenomenos clasicos (en sus versiones espaciales) que son la reflexion de una onda sobre un espejo y su trasformacion en un cristal. Ademas, mostramos que los dos son intimamente relacionados. El equivalente temporal de un espejo produje instantaneamente desde el medio entero una onda retornada en el tiempo, es decir cuya evolucion temporal es invertida comparado a la onda inicial. Una variante monofrecuencial de este espejo queda estudiada tambien. Posee estrechos vinculos con el concepto de Phase Conjugation (conjugacion de fase), usado en Optica para hacer retornamiento temporal de ondas monocromaticas. Mostramos que la modulacion temporal implicada constituye el equivalente de un cristal para las ondas et estudiamos las caracteristicas generales de ondas en estos medios. Sondeamos los limites de esas analogias espaciotemporales de cuyos obviamente el principio de causalidad es un elemento mayor y que revelan diferencias interesantes entre los conceptos presentados y sus equivalentes espaciales
L’universalita dei fenomeni ondulatori classici e in larga misura descritta dalla struttura dell’equazione di d’Alembert. In quest’equazione, le variabili spaziali e temporali svolgono ruoli analoghi. Nell’opera seguente rivisitiamo questa ben nota analogia introducendo nuovi concetti sul controllo temporale della propagazione delle onde. Questi concetti possono essere interpretati come trasposizione di fenomeni ondulatori spaziali standard nell’ambito temporale, sostituendo le variazioni spaziali delle proprieta del mezzo con le variazioni temporali corrispondenti. Usando delle onde sulla superficie di un liquido come modello fisico, facciamo fede della rilevanza di quell’approccio e mostriamo teoricamente la generalizzazione a tutti i tipi di onde classiche, governate da equazioni simili a quella di d’Alembert. Questa analogia viene studiata nell’ambito di due fenomeni ondulatori ben noti (nella loro versione spaziale) : la riflessione delle onde generata da un specchio e la loro trasformazione generata da un cristallo. Mostriamo inoltre che i due concetti sono intimamente vincolati. L’equivalente temporale di un specchio porta alla generazione in tutto lo spazio di un’onda restituita nel tempo, vale a dire un’onda di cui l’evoluzione temporale e invertita in relazione all’onda originale. In questa tesi viene presentata anche una variante monofrequenziale di questo specchio temporale istantaneo che possiede legami stretti con il concetto di coniugazione di fase usato in ottica per invertire nel tempo onde monocromatiche. Mostriamo in questo lavoro che la modulazione temporale periodica del mezzo in questione costituisce, per le onde, l’equivalente temporale di un cristallo e ne studiamo le proprieta generali. In questa tesi, cerchiamo di sondare i limiti dell’analogia spaziotemporale, di cui il principio di causalita ne e l’essenziale e che rivelano differenze interessanti tra i concetti presentati e i loro equivalenti spaziali

Full textThis work is an inquiry into the current understanding of experimental single-mode Faraday waves, from the perspective of linear stability theory. At low frequency, the characteristic wavelength is of the order of the cell dimensions, and theoretically the wavelengths associated with the modes available for excitation are discretized by the sidewall boundary condition. Mathematically, the condition which eases manipulation is a stress-free sidewall condition, which is unrealistic due to viscous boundary layers and capillary hysteresis. We report the experimental investigation of a low frequency system designed to approximate this condition, by careful choice of the fluid liquids and thereby increasing the relative importance of the interior damping. The design has permitted close connection between the experimental thresholds and the predictions, contrasting the traditional approach of phenomenologically measuring the mode dissipation and treatment as a single degree of freedom system. Non-ideal behavior of the sidewall persists, evident by the contact meniscus and the sidewall film which is formed during wave excitation. The presence of these non-idealities is translated to trends in the deviation between the observed and predicted thresholds, depending upon the mode structure and wave periodicity. The presence of harmonically excited waves from the meniscus seems to result in observation of amplitudes consistently lower than the predictions, indicating a mixed resonance between the parametric instability and the forced meniscus oscillations. Furthermore, it is seen this interaction can be adjusted by excitation with two commensurate parametric frequencies

Full textHigh frequency combustion instabilities ( ˜few kHz) in rocket engines imply a coupling between chamber acoustics and combustion. This study debates on the influence of a transverse acoustic field on the atomization of an air-assisted jet. A coaxial injector is placed at a pressure anti-node (PA) or velocity anti-node (VA) of a stationary plane acoustic wave with maximum fluctuation of 3600 Pa. At hte Pa, the acoustic wave modulates the annular gaseous flow and can induce the emission of intense vortices, which leads to a early shear-stress instability. Placed at a VA, non linear effects due to radiation pressure flattened the jet under the form of a sheet. A criterion, established from a radiation acoustic Bond number, determines its apparition. The sheet is atomised under the action of intrinsic sheet instabilities, Faraday instability and break-up of membranes. Acoustic effects organize the spray: amass and low speed droplets stay or go to the velocity anti-node
