Lombard, Julien. "Nanobulles et nanothermique aux interfaces." Thesis, Lyon 1, 2014. http://www.theses.fr/2014LYO10233/document.
Nanobubbles produced around metal nanoparticles heated by a laser pulse have received an increasing interest over the last decade. This interest is motivated by the possible use of those nanobubbles as an agent for cancer therapy. Existing studies are mainly experimental and a complete description of the mechanisms controlling the nanobubbles generation and evolution is still lacking. The aim of this thesis is to answer those fundamental issues by numerically solving a model based on the conservation equations inside the fluid (mass, momentum and energy). This model accounts for the thermodynamics of the fluid, capillary effects and a thermal interface resistance across the particle-fluid interface. Solving this model gives information about the thermodynamics of the fluid before and after its vaporization, which allows for the description of the bubbles dynamics. Then, we can define a criterion for bubbles generation, which corresponds to the crossing of the spinodal temperature of the fluid. Finally, we investigate the role played by the interface thermal resistance arising from electron-phonon couplings between a metal and a dielectric. We present some preliminary results concerning the heating of a fluid with core-shell nanoparticles
Saadi, Bachir. "Contrôle électromagnétique des transferts de masse aux interfaces liquide/liquide." Phd thesis, Grenoble INPG, 2006. http://tel.archives-ouvertes.fr/tel-00068975.
Cette thèse s'intéresse à l'utilisation des forces électromagnétiques pour agiter, sans contact matériel, le cœur du bain et l'interface afin de contrôler voire d'augmenter la cinétique de ces transferts. Pour cela, deux installations expérimentales complémentaires ont été utilisées :
La première a permis de mesurer le transfert d'Indium initialement dissous dans du mercure vers un électrolyte de couverture et le champ des vitesses dans le mercure. Les expériences réalisées ont permis, d'une part de déterminer la topologie des champs de vitesses des écoulements dans le bain de mercure, et d'autre part de compléter les lois d'évolution de la cinétique de transfert en fonction de l'intensité du champ magnétique. Cette évolution est corrélée aux comportements dynamiques de la surface du mercure.
La seconde installation a permis de caractériser le transfert d'un élément (Pb, Zr ou Ce) initialement contenu dans un sel fluoré vers une matrice d'antimoine contenant du lithium. Il apparaît que les cinétiques des transferts sont toutes très rapides. Le dispositif proposé est particulièrement efficace lors de transfert du Cérium (limité par l'interface) mais sans action lors de transfert de Zirconium.

A new electromagnetic process is set up in order to improve the mass transfers between a molten metal and a slag. The principle of the process consists to melt and stir the metal in an cold-crucible induction furnace supplied with a two-frequency alternating current. This inductive current contains a basic frequency to heat and ensure an electromagnetic stirring of the bulk metal as well as a low modulation frequency in order to destabilize the interface metal - slag. Such an inductive current is obtained by modulating the input instruction of a standard induction generator using a sinusoidal signal delivered by a function generator. A study of the hydrodynamic behaviour of the free surface of gallium in such a two-frequency induction system showed that it is possible to excite axisymetric oscillation modes when the modulation frequency of the inductive current corresponds to the eigenfrequency of the oscillation modes. The maximum amplitudes and the frequency of the deformations of the free surface were measured according to the modulation parameters imposed on the induction generator. The experimental features of the free surface oscillations agree qualitatively with those predicted by the analytical model. A system of detection of resonance, without contact with the free surface, was set up in order to detect the deformations of the free surface generated by the excitation of the oscillation modes. The aptitude of the process to improve the kinetics of transfer of zirconium from a fluorinated salt to a molten metal containing aluminium as reducing agent was studied. Experiments of transfer were carried out without and with modulation of the inductive current. They showed that, for a fixed value of the current, the transfer can be accelerated thanks to the interfacial agitation generated by the modulation of the inductive current
Avrit, Antoine. "Étude du comportement d’ablation d’une structure solide par un jet liquide chaud." Electronic Thesis or Diss., Université de Lorraine, 2023. http://www.theses.fr/2023LORR0281.
Safety studies for fast neutron reactors with sodium led to the development of mitigation systems for severe accidents. During a hypothetical severe accident, at least part of the reactor's core melts, leading to the formation of corium. The corium has to be relocated to prevent any criticality problems. Therefore, transfer tubes were integrated to the design of the core to relocate the corium from the core to a core-catcher. A jet of corium exits the transfer tubes and spreads on the core-catcher, allowing a better cooling of the corium. However, thermal ablation of the core-catcher will occur as the temperature of the corium is very high (~ 2000 - 3000 K). Thus, the core-catcher has to be dimensioned to prevent any breach due to the ablation. Experiments were performed during a previous thesis to improve understanding of the phenomenon of ablation by a free-surface jet, with a bench called HAnSoLO (Hot AblatioN of a SOlid by a Liquid - Observations). New results were obtained in the present work to address additional phenomenologies. For instance, the ablation of a solid by an immersed jet was studied. This is another situation that could occur in the real case. The effect of the roughness of the impacted solid was also addressed, and it was shown that taking roughness into account is important to design the core-catcher. All these results were used to validate a CFD code. In particular, the ablation result obtained through the numerical simulations were very similar to the experimental results for the immersed jet case. The simulations and experiments will be completed in the future to numerically treat the ablation of a metallic solid by a corium jet under reactor conditions

Les premiers travaux réalisés ont porté essentiellement sur la simulation numérique de la DM appliquée à l'étude de la thermodiffusion, ou effet Soret, en fluide libre et en milieu poreux. De ce travail est notamment ressortit que le confinement géométrique n'affecte pas le facteur de thermodiffusion et que l'effet Soret dans les mélanges d'alcanes est principalement du à un effet de masse.
Dans l'optique mentionnée dans l'introduction, trois thèmes ont été ensuite abordés. Deux thèmes ont trait à la dynamique moléculaire classique, l'un concernant l'influence de la description des interactions sur les propriétés thermophysiques dans les fluides et l'autre la simulation/modélisation de propriétés de transport du fluide de Lennard-Jones et son application aux corps réels. En particulier il a été montré qu'un état correspondant existait entre les potentiels de type Mie et Exponentiel au niveau des propriétés de transport et que Lennard-Jones (LJ) était un bon compromis pour les corps simples. De même ont été développées des corrélations basées sur le fluide de LJ permettant d'estimer les propriétés de transport. Cette approche s'est avérée particulièrement efficace quant à l'estimation de la viscosité des gaz acides (H2S, CO2). Le troisième thème concerne la modélisation macroscopique de la dynamique de fluides multiconstituants en milieux poreux pour lequel une approche de type équation Darcy généralisée par espèce a été proposée.
Les activités en cours concernent la prédiction/modélisation de fluides plus complexes avec ou sans interfaces mais également des aspects liés aux simulations multi-échelles/multi-physiques au travers d'un couplage direct entre mécanique des fluides numérique et DM. En particulier à été proposée une approche permettant l'étude de la thermogravitation dans les gisements par simulation moléculaire.

This thesis is devoted to the study of interfacial thermal transport at the nanoscale where Fourier’s law is not valid. This is because, at this scale, phonon mean free path becomes smaller to the characteristic length of the system, thus the heat transfer is no longer diffusive but rather ballistic. As a consequence, the thermal boundary resistance (TBR) becomes a determinant factor in heat transfer. The goal of this thesis is, firstly, to study phonon transmission and predict the thermal boundary conductance at interface between two solids. To this end, we have developed a new approach, which combines lattice dynamics calculations and inputs from ab initio, and we have applied our LD model to two types of solid structures: the face-centered cubic (FCC) crystal solid and the diamond-like crystal solid.Secondly, we aim to quantify the phononic contribution in heat transfer across a nanometric vacuum gap that separates two solids. We have used this ab initio LD model to predict the contribution of phonons in the heat transfer across a vacuum gap in two systems: the Au/vacuum-gap/Au and the Si/vacuum-gap/Si. Our results indicate that phonons do contribute significantly to heat transfer across a nanometric/subnanometric vacuum gap. Finally, we have investigated heat transfer in a system made of a core-shell nanoparticle (NP) immersed in water and heated by a laser pulse. We have used the four temperatures model, we have solved numerically the heat transfer equations in the system, taking into account the thermal boundary resistance (TBR) and the interfacial electron-phonon coupling
Ronzani, Filippo. "Réactions d’oxydation photosensibilisée : espèces transitoires réactives et mécanismes aux interfaces." Thesis, Pau, 2013. http://www.theses.fr/2013PAUU3020/document.
The main aim of the work carried out during this PhD project was to develop, characterize and analyze original materials for photosensitized oxidation reactions. Particular attention was paid to the determination of the photophysical properties of the selected photosensitizers (PSs) and the effect induced by the immobilization on an inert support (silica). The reactive species formed upon irradiation were identified and analyzed. Singlet oxygen production was monitored by two complementary methods. The solid-supported sensitizers were employed, in the form of either monoliths or powders, for the photooxidation of dimethyl sulfide at the gas-solid interface and of -terpinene at the liquid-solid interface. Singlet oxygen was the main reactive oxygen species formed by the selected PSs; nonetheless, the reaction products were analyzed and other possible mechanistic scenarios investigated

In the last two decades, interest in Brain-Computer Interfaces (BCI) has tremendously grown, with a number of research laboratories working on the topic. Since the Brain-Computer Interface Project of Vidal in 1973, where BCI was introduced for rehabilitative and assistive purposes, the use of BCI has been extended to more applications such as neurofeedback and entertainment. The credit of this progress should be granted to an improved understanding of electroencephalography (EEG), an improvement in its measurement techniques, and increased computational power.Despite the opportunities and potential of Brain-Computer Interface, the technology has yet to reach maturity and be used out of laboratories. There are several challenges that need to be addresses before BCI systems can be used to their full potential. This work examines in depth some of these challenges, namely the specificity of BCI systems to users physical abilities, the robustness of EEG representation and machine learning, and the adequacy of training data. The aim is to provide a BCI system that can adapt to individual users in terms of their physical abilities/disabilities, and variability in recorded brain signals.To this end, two main avenues are explored: the first, which can be regarded as a high-level adjustment, is a change in BCI paradigms. It is about creating new paradigms that increase their performance, ease the discomfort of using BCI systems, and adapt to the user’s needs. The second avenue, regarded as a low-level solution, is the refinement of signal processing and machine learning techniques to enhance the EEG signal quality, pattern recognition and classification.On the one hand, a new methodology in the context of assistive robotics is defined: it is a hybrid approach where a physical interface is complemented by a Brain-Computer Interface (BCI) for human machine interaction. This hybrid system makes use of users residual motor abilities and offers BCI as an optional choice: the user can choose when to rely on BCI and could alternate between the muscular- and brain-mediated interface at the appropriate time.On the other hand, for the refinement of signal processing and machine learning techniques, this work uses a Riemannian framework. A major limitation in this filed is the EEG poor spatial resolution. This limitation is due to the volume conductance effect, as the skull bones act as a non-linear low pass filter, mixing the brain source signals and thus reducing the signal-to-noise ratio. Consequently, spatial filtering methods have been developed or adapted. Most of them (i.e. Common Spatial Pattern, xDAWN, and Canonical Correlation Analysis) are based on covariance matrix estimations. The covariance matrices are key in the representation of information contained in the EEG signal and constitute an important feature in their classification. In most of the existing machine learning algorithms, covariance matrices are treated as elements of the Euclidean space. However, being Symmetric and Positive-Definite (SPD), covariance matrices lie on a curved space that is identified as a Riemannian manifold. Using covariance matrices as features for classification of EEG signals and handling them with the tools provided by Riemannian geometry provide a robust framework for EEG representation and learning

The aim of this thesis, in collaboration with Saint-Gobain within the framework of a CIFRE funding, is the study of heat transfer at the interface between microscopic objects from which isolation materials are made. During this thesis we developed two new instruments, allowing to investigate the heat transfer between two microscopic glass objects. The first instrument is a scanning probe microscope using a thermosensitive probe (SThM probe) allowing to make a very local temperature measurement or to produce a local heating of a sample in contact with the probe. We used this probe in an unusual way, by gluing a 20µm diameter glass bead on its thermosensitive end, by placing it above a flat glass surface whose temperature is different from that of the bead, and by studying the temperature at the top of this bead as the distance bead-to-plan varies. The "approach curves" obtained in this way and a model using a thermoelectric analogy that we propose allow to give a first estimation of the thermal resistance of contact in a sphere-plane geometry. The second instrument is a new infrared thermography device. It is a contactless method which allows to produce images in the mid-infrared with a spatial resolution better than the diffraction limit, but also to carry out a dynamic measurement of the cooling of a system made of one or more micrometric glass fibers, after a short and local heating by absorption of a pulsed ultraviolet laser. Comparison of these curves recorded on a single fiber or on two crossing fibers makes it possible to obtain an information on the thermal resistance of contact at the crossing of the two fibers. A semi-analytical model that we developed allows us to reproduce these trends on a single fiber, while a perturbative approach exploiting the one-fiber model allows us to reproduce the spatiotemporal evolution of heat within a system of two fibers in contact

Marçais, Johanna. "Transferts des polluants organiques persistants de l'atmosphère aux milieux aquatiques de montagne." Thesis, Université Grenoble Alpes (ComUE), 2017. http://www.theses.fr/2017GREAA005/document.
Atmospheric sources of persistent organic pollutants (POPs) are relatively well known. Once in this compartment under both gas and particulate forms, these compounds are carried on more or less long range. Then, pollutants are eliminated by dry (aerosol) or wet (rain, snow) depositions according to meteorological conditions. The global planetary distribution of POPs affects all environments and mountain aquatic environments are not spared. Several studies on European high altitude mountain lakes have reported the presence of Polychlorinated Biphenyls (PCBs) and Polycyclic Aromatic Hydrocarbons (PAHs). In these remote areas, the atmospheric compartment is the unique source of pollution. Few studies were conducted in order to understand and identify transfer mechanisms at the air-water interface in mountain. So, this thesis focused on POP exchanges at the air-water interface. In order to characterize atmospheric influence on aquatic compartment and calculate pollutant fluxes, two separate water systems were studied: a high altitude lake (Muzelle lake, Oisans) and an alpine river (Arc, Maurienne valley). Two POP families were targeted for their different physicochemical properties: PAHs and PCBs.In these mountain environments with limited access and energy, passive sampling strategy was chosen. Samplers were improved, developed in the lab or used to distinctly collect all POP forms in the air (gas, particulate, dry and wet depositions) and water (dissolved, particulate). A comparison of different atmospheric passive samplers was conducted to define the most reliable and representative. The air-water transfer studies were realized on the high altitude lake over two summer periods (2014 and 2015) and over a two years monitoring (2014 to 2016) in the alpine river. So, the atmospheric role on the alpine lake in summer was defined and air-water flux exchanges were calculated. As the alpine river is a more complex water system for the air-water transfers study and quantification, in a first time a space-time contamination monitoring was conducted along the river and a first approach was applied to calculate pollutant fluxes at the interface

The use of predictive models of the contamination of food by substances originating from packaging materials is encouraged to demonstrate the compliance of food contact materials in Europe and in the United States, as well as to assess the exposure of the consumer to these substances. This work aims to test the consistency of the boundary conditions between the packaging material and food used in predictive models and to improve our understanding of molecular mechanisms, which control the involved mass transport properties: diffusion coefficient, D, partition coefficient,. Reference data were obtained mainly for low density polyethylene in contact with a slightly agitated liquid food simulant of intermediate polarity: ethanol or methanol. Four series homologous with molecules were studied including: i) molecules resembling chains of polymer and with variable polarity (linear alkanes and alcohols), ii) of hindered phenolic antioxidants and iii) of the fluorescent dyes. The boundary layer approximation, also known as stagnant film approximation, was tested from macroscopic desorption kinetics and starting observations in laser scanning confocal microscopy. On the basis of the methodology described in Vitrac and Hayert (2006), values of the mass transfer coefficient at the interface, h, were in particular identified independently of D values. The analysis of the scaling laws of D and h according to the molecular mass, M, however showed similar dependences of the two properties, with M in the form with. The scaling law associated to h suggests the existence of a mass transfer resistance located at the extreme surface on the polymer side and that is independent of its thickness. The existence of a boundary layer matter on the liquid side was in addition confirmed in confocal microscopy. The reversibility and linearity of the sorption/desorption isotherms in plastic material and in the simulant were verified only for materials formulated after processing. For materials formulated before processing (case of commercial materials), significant deviations were identified: trapping of diffusants and possible adsorption at high concentrations. Rigorously taking into account the entropic contribution in the Flory-Huggins approach made it possible to propose a first predictive model of starting from the only solubility coefficients tabulated by Van Krevelen (1991). This approach was satisfactorily tested for two polymers, two simulating and forty diffusing. Because it does not require any preliminary identification, it is more reliable and robust than alternative group contribution methods (Baner et al. , 1991 ; Tehrany and Desobry, 2005). Finally, the feasibility of a chemical modification of the extreme surface at molecular scale by plasma treatment was analyzed. For an increase of 50% of the atomic oxygen content on a thickness of 10 nm, a reduction of the contact angle water-polyethylene-air of 50% was measured but was not associated to a significant modification of desorption kinetics of alkanes in ethanol

Within the industrial framework of the gas waste processing, in particular H2S, the optimization of the Clauspol type units requires the substitution of random packing by structured packing. Structured packing are of recent use, and it is necessary to acquire a better knowledge of the hydrodynamics and mass transfer on such structures, which are complex because of their geometries. Gas-liquid mass transfer is studied for thin films trickling down a tilted plane surface or corrugated one. Local gas side and liquid side mass transfer coefficient, kG and kL, as well as the specific interfacial area, a, are estimated by means of experiments of reactive absorption of CO2 in a sodium hydroxide solution. The dependence of these mass transfer characteristic parameters is explored versus the geometrical properties of the streaming surfaces and the local hydrodynamic properties characterized by the flow rate and liquid film thickness. The mean film thickness is measured using an ultrasonic probe method and by the analysis of Residence Time Distribution. It is small, thinner than 1. 10-3m for a liquid film trickling over plane surface inclined at 30ʿ. On a corrugated surface, while working for angles stronger, up to 70ʿ, the thickness is larger inducing a reduction of the liquid flow velocity. Thus, the total increase in the kLa product observed while passing from a flow on a plane surface to a flow on a corrugated one, is primarily related to the effects of the corrugated geometry on the specific interfacial area. Moreover, the liquid side mass transfer coefficient kL is not very disturbed in the studied range of Reynolds numbers. It is also not very sensitive to the film geometry

The dynamic of the gesture is not used a lot in the domain of human-computer interaction,while it can help to define some simple heuristics to analyze the intents of users.Its first use is related to transfer functions for isotonic devices. Those functions establisha relationship between the gesture of the user, executed in motor space with the pointingdevice (i.e. a mouse), and the movement of the pointer in the visual space. The transferfunctions used by modern operating systems are still not well known, even if somestudies have shown they have an impact on user’s performance. To characterize thosefunctions, we have developed an electronic device which simulates a real mouse, and thatcan retrieve the transfer functions of any system. We have then exposed the functions ofthe Windows, Linux and Mac systems, and we observed some visible differences betweenthose functions. We have then tried to optimize those functions by reducing their numberof degrees of freedom. By varying those parameters in an exhaustive way, we have thenobserved some significant differences that show there is a family of functions for whichperformances are optimal. Finally, we were interested in the use of the dynamic of thegesture in another context : the generation of discrete events, useful when dealing withcontact-less interfaces, like the Kinect. We have shown that it is possible to distinguishbetween picking and drag’n’drop in a 3D interaction task. The technique is then improvedin the case of small size targets, and its application in a 2D interaction context isevaluated

The intuitive use of complex interfaces is apprehended by a schema induction protocol, due to its interaction with prior knowledge. The protocol is specified to account for multi-states interfaces and for their decomposition into separate informational attributes. We obtain two dominant empirical patterns that are schema induction, accounting for non intuitive states, non familiar tasks, as well as for accessible states for experiential users, and inaccessible states for rational ones, and transfer, accounting for familiar tasks and intuitive states. Patterns of inoperant analysis and negative induction effect are also obtained that justify the diagnosing approach and its relevance in current frameworks for the design of intuitive interfaces
