Abstract:

Supersonic incoming flow has a large momentum, which makes it difficult for transverse jets to have a large penetration depth due to the strong compression of the incoming flow. This impacts the mixing efficiency of the jet in the supersonic combustor. This paper proposes a method to improve the mixing efficiency of a rectangular flow field model using pulsed energy deposition, which is verified numerically. In the simulations, the Navier–Stokes equations with an energy source are solved to simulate the effects of energy deposition with various distributions on the fuel mixture. The results show that the energy deposition increases the turbulent kinetic energy, which enlarges the scale of the flow vortex and improves the fuel mixing performance. The energy deposition is distributed upstream and significantly improves the mixing performance. Energy deposition can improve the penetration depth of fuel, which is more significant when the energy deposition is distributed downstream of the jet orifice. The energy deposition also slightly reduces the total pressure recovery coefficient. In general, an energy deposition that is distributed upstream of the jet has the best effect on the mixing efficiency.

Abstract:

The high-latitude ionosphere is a dynamic region, in which a variety of phenomena including particle precipitation, currents and waves contribute to the energy budget. In this thesis, statistical and case studies of ion frictional heating are presented, including investigations into the dependence of enhanced ion temperature on time and altitude. The relationship between parallel ion temperature and ion velocity is compared to simplified forms of the ion energy balance equation. In addition, the generation mechanisms of atmospheric gravity waves are studied by means of measurements made during the WAGS campaign of October 1985. The results indicate that auroral precipitation can influence frictional heating events to a greater extent than has previously been realised and that during frictional heating the molecular content of the lower ionosphere is enhanced, affecting the electron density. Any analysis which takes no account of the modified composition underestimates the parallel ion temperature, particularly between 200 and 300 km altitude. The relationship between ion velocity and parallel ion temperature is most easily explained by an anisotropic ion velocity distribution, consistent with resonant charge exchange collisions. The relationship varies with altitude, however, possibly due to ion-ion collisions. An experimental method is described by which the temperature anisotropy can be obtained directly and early results are discussed. For the investigation of atmospheric gravity waves and their sources, HF Doppler observations in the UK enabled wave speeds and azimuths to be deduced, whilst EISCAT simultaneously observed the possible source region. Although the study was characterised by moderate activity, more active days showed higher phase speeds and southerly azimuths. Some of these waves may have originated at high latitudes during positive bay activity, when both Joule heating and the Lorentz force contributed to wave generation.

Abstract:

La filamentation laser est un régime de propagation optique spectaculaire atteint pour des impulsions dont la puissance crête excède quelques gigawatts dans l’air. Le filament se forme sous l’action de l’effet Kerr optique du milieu traversé qui tend à auto-focaliser le faisceau jusqu’à ce que l’intensité résultante atteigne le seuil d’ionisation du milieu par absorption multiphotonique. Une compétition dynamique complexe s’établit alors entre l’effet Kerr, d’une part, et la diffraction, l’absorption non-linéaire de l’énergie laser et l’effet défocalisant du plasma d’autre part. Il en résulte une réorganisation du profil du faisceau, caractérisée par un coeur mince (100 µm) et intense (10^18 W/m²) pouvant se maintenir sur une distance égale à plusieurs longueurs de Rayleigh. Lorsque la puissance initiale de l’impulsion dépasse largement le seuil de filamentation, on assiste à la formation de plusieurs filaments co-propagatifs au sein du même faisceau, chacun de ces multifilaments possédant des caractéristiques physiques proches de monofilaments isolés. Au cours de sa propagation dans l’air, le filament transfère une partie de l’énergie laser au milieu, principalement via l’excitation rotationnelle Raman des molécules d’air, l’ionisation de l’air et l’effet de Bremsstrahlung inverse au sein du plasma. Cette énergie est redistribuée au cours de la nanoseconde suivant le passage du laser, principalement sous forme d’énergie translationnelle des molécules d’air, c’est-à-dire de chaleur. Le milieu réagit à ce chauffage rapide par la formation d’une onde de pression cylindrique, qui ramène le système à l’équilibre de pression en éjectant de la matière du centre. Il en résulte la formation d’un canal d’air sous-dense et chaud, qui se résorbe par diffusion à des échelles de temps supérieures à la milliseconde. Ma thèse s’est en premier lieu focalisée sur l’étude et l’optimisation du dépôt d’énergie dans l’air par filamentation. J’ai ainsi étudié l’influence des différents paramètres laser, comme l’énergie de l’impulsion, la focalisation employée et la durée d’impulsion sur la densité d’énergie déposée. Pour ce faire, j’ai employé plusieurs diagnostics complémentaires : mesure des ondes de pression à l’aide de microphones, analyse du plasma de filament par spectroscopie et mesure résolue en temps des canaux sous-dense par interférométrie. J’ai ainsi montré en régime de monofilamentation qu’au-delà d’une certaine énergie laser initiale, le dépôt d’énergie devient si important qu’une onde de choc est générée en lieu et place d’une onde sonore, et que les canaux sous-denses résultant ont des durées de vie de l’ordre de 100 ms. J’ai également étudié et caractérisé le régime de multifilamentation à haute énergie, montrant qu’en focalisant modérément l’impulsion, les filaments se réorganisent dans la zone focale pour former des structures plus larges générant un plasma dix fois plus dense que les filaments. Les effets hydrodynamiques engendrés par filamentation entraînent un abaissement transitoire du seuil de claquage électrique de l’air le long du trajet de l’impulsion laser, permettant ainsi de déclencher et de guider des décharges électriques. La seconde partie de ma thèse avait pour objet l’étude et l’optimisation de telles décharges guidées pour la mise au point d’une antenne plasma radio-fréquence, de commutateurs haute tension sans contact ou encore d’un paratonnerre laser. Pour ce faire, j’ai développé et construit un diagnostic plasma interférométrique à deux couleurs permettant de caractériser la durée de vie des plasmas générés. J’ai également participé à une expérience de principe démontrant la possibilité de réaliser une antenne plasma RF à partir d’un filament laser. Enfin, j’ai participé à diverses études expérimentales prospectives dans l’optique du développement d’un paratonnerre laser
Laser filamentation is a spectacular optical propagation regime appearing for pulses of which peak power exceeds a few GW in air. Filament forms due to the optical Kerr effect, which tends to self-focus the beam until intensity reaches the medium ionization threshold by multiphoton absorption. A complex dynamic competition is then established between the Kerr effect on the one hand, and diffraction, nonlinear absorption and plasma defocusing effect on the other hand. This results in a reorganization of the beam profile, characterized by a thin (100 µm) and intense (10^18 W/m²) core able to propagate over a distance much longer than the Rayleigh length. When the initial pulse peak power largely exceeds filamentation threshold, several co-propagating filaments are formed in the same beam, with each of these multifilaments sharing physical properties of isolated single filaments. While propagating in air, filaments transfer a portion of the laser energy to the medium, mainly through Raman rotational excitation of air molecules, ionization and inverse Bremsstrahlung in the plasma. This energy is redistributed in one nanosecond and almost entirely converted into air molecule translational energy, that is heat. The medium reacts to this rapid heating by launching a cylindrical pressure wave that brings the system back to pressure equilibrium by ejecting matter from the center. This results in the formation of a hot underdense air channel, which slowly resorbs by diffusion at timescales > 1 ms. My work as a Ph. D. Student first focused on the study and the optimization of laser energy deposition in air by filamentation. Thus, I investigated the influence of laser parameters such as pulse energy, focusing strength or pulse duration on deposited energy. To this purpose, I used several complementary diagnostics: study of pressure waves using microphones, characterization of the filamentation plasma by means of spectroscopy and time resolved study of underdense air channels using interferometry. I demonstrated in the single filamentation regime that above a given pulse energy, energy deposition becomes so important that the medium generates a shock wave instead of a sound wave, and that underdense channels can last for more than 100 ms. I also studied and characterized the high energy multifilamentation regime, showing that moderately focusing the pulse leads to a reorganization of filaments in the focal zone, generating large structures with a resulting plasma ten times denser than filaments. Filamentation-induced hydrodynamic effects lead to a transient reduction of the air breakdown voltage along the path of the laser pulse, enabling one to trigger and guide electric discharges. The second part of my thesis focused on the study and the optimization of such guided discharges for the design of a radio-frequency plasma antenna, contactless high-voltage switches or a laser lightning rod. To this purpose I developed and built an interferometric plasma diagnostic, allowing to measure the lifetime of generated plasmas. I also contributed to the proof of principle for a filament induced plasma antenna emitting RF signal. Finally, I took part to prospective experimental studies for the development of a laser lightning rod

Abstract:

Technological progress is determined to a great extent by developments of novel materials from new combinations of known substances with different dimensionality and functionality. We investigate the development of 3D ‘hybrid’ nanomaterials by utilizing graphene based systems coupled with transition metal oxides (e.g. manganese oxides MnO2 and Mn3O4). This lays the groundwork for high performance electrochemical electrodes for alternative energy owing to their higher specific capacitance, wide operational window and stability through charge-discharge cycling, environmental benignity, cost effective, easily processed, and reproducible in a larger scale. Thus far, very few people have investigated the potential of combining carbon sheets that can function as a supercapacitor in certain systems with transition metals that have faradaic properties to create electrochemical capacitors. Previous work by Wang et al. has focused on the structural combination of Mn3O4 and graphene based materials,1 and research by Jafta et al. studied the electrochemical properties of MnO2 with GO.2 We find that both physical and chemical attachment of manganese oxide on graphene allows for electrical interplay of the materials as indicated in electrochemical analysis and Raman spectroscopy. Attachment of the two materials is also characterized by scanning electron microscopy and X-ray diffraction.

Abstract:

Increasing worldwide demand for petroleum motivates greater efficiency, safety, and environmental responsibility in upstream oil and gas processes. The objective of this research is to improve these areas with advanced control methods. This work develops the integration of optimal control methods including model predictive control, moving horizon estimation, high fidelity simulators, and switched control techniques applied to subsea riser slugging and managed pressure drilling. A subsea riser slugging model predictive controller eliminates persistent offset and decreases settling time by 5% compared to a traditional PID controller. A sensitivity analysis shows the effect of riser base pressure sensor location on controller response. A review of current crude oil pipeline wax deposition prevention, monitoring, and remediation techniques is given. Also, industrially relevant control model parameter estimation techniques are reviewed and heuristics are developed for gain and time constant estimates for single input/single output systems. The analysis indicates that overestimated controller gain and underestimated controller time constant leads to better controller performance under model parameter uncertainty. An online method for giving statistical significance to control model parameter estimates is presented. Additionally, basic and advanced switched model predictive control schemes are presented. Both algorithms use control models of varying fidelity: a high fidelity process model, a reduced order nonlinear model, and a linear empirical model. The basic switched structure introduces a method for bumpless switching between control models in a predetermined switching order. The advanced switched controller builds on the basic controller; however, instead of a predetermined switching sequence, the advanced algorithm uses the linear empirical controller when possible. When controller performance becomes unacceptable, the algorithm implements the low order model to control the process while the high fidelity model generates simulated data which is used to estimate the empirical model parameters. Once this online model identification process is complete, the controller reinstates the empirical model to control the process. This control framework allows the more accurate, yet computationally expensive, predictive capabilities of the high fidelity simulator to be incorporated into the locally accurate linear empirical model while still maintaining convergence guarantees.

Abstract:

The direct epitaxial growth of multilayer BN by atomic layer deposition is of critical significance forfo two-dimensional device applications. X-ray photoelectron spectroscopy (XPS) and low energy electron diffraction (LEED) demonstrate layer-by-layer BN epitaxy on two different substrates. One substrate was a monolayer of RuO2(110) formed on a Ru(0001) substrate, the other was an atomically clean Ni(111) single crystal. Growth was accomplished atomic layer deposition (ALD) cycles of BCl3/NH3 at 600 K substrate temperature and subsequent annealing in ultrahigh vacuum (UHV). This yielded stoichiometric BN layers, and an average BN film thickness linearly proportional to the number of BCl3/NH3 cycles. The BN(0001)/RuO2(110) interface had negligible charge transfer or band bending as indicated by XPS and LEED data indicate a 30° rotation between the coincident BN and oxide lattices. The atomic layer epitaxy of BN on an oxide surface suggests new routes to the direct growth and integration of graphene and BN with industrially important substrates, including Si(100). XPS and LEED indicated epitaxial deposition of h-BN(0001) on the Ni(111) single crystal by ALD, and subsequent epitaxially aligned graphene was deposited by chemical vapor deposition (CVD) of ethylene at 1000 K. Direct multilayer, in situ growth of h-BN on magnetic substrates such as Ni is important for spintronic device applications. Solid-state electrolytes (SSEs) are of significant interest for their promise as lithium-ion conducting materials but are prone to degradation due to lithium carbonate formation on the surface upon exposure to atmosphere, adversely impacting Li ion conduction. In situ XPS monitored changes in the composition of the SSE Li garnet (Li6.5La3Zr1.5Ta0.5O12, LLZTaO) upon annealing in UHV and upon Ar+ ion sputtering. Trends in core level spectra demonstrate that binding energy (BE) calibration of the Li 1s at 56.4 eV, yields a more consistent interpretation of results than the more commonly used standard of the adventitious C 1s at 284.8 eV. Annealing one ambient-exposed sample to >1000 K in UHV effectively reduced surface carbonate and oxygen, leaving significant amounts of carbon in lower oxidation states. A second ambient-exposed sample was subjected to 3 keV Ar+ ion sputtering at 500 K in UHV, which eliminated all surface carbon, and reduced the O 1s intensity and BE. These methods present alternative approaches to lithium carbonate removal than heating or polishing in inert atmospheres and are compatible with fundamental surface science studies. In particular, the data show that sputtering at mildly elevated temperatures yields facile elimination of carbonate and other forms of surface carbon. This is in contrast to annealing in either UHV or in noble gas environments, which result in carbonate reduction, but with significant remnant coverages of other forms of carbon.

Abstract:

AbstractWire arc additive manufacturing allows the production of metallic parts by depositing beads of weld metal using arc-welding technologies. This low-cost additive manufacturing technology has the ability to manufacture large-scale parts at a high deposition rate. However, the quality of the obtained parts is greatly affected by the various thermal phenomena present during the manufacturing process. Numerical simulation remains an effective tool for studying such phenomena. In this work, a new finite element technique is proposed in order to model metal deposition in WAAM process. This technique allows to gradually construct the mesh representing the deposited regions along the deposition path. The heat source model proposed by Goldak is adapted and combined with the proposed metal deposition technique taking into account the energy distribution between filler material and the molten pool. The effectiveness of the proposed method is validated by series of experiments, of which an example is detailed in this paper.

Abstract:

Abstract In the past few years, the Extreme High-Speed Laser Material Deposition (EHLA) process has been used as a coating technology alongside conventional processes due to its unique process characteristics and is an economical and sustainable alternative to traditional technologies. The essential characteristic of the process is that the main energy is absorbed by the powder particles so that they reach the substrate surface in a molten state. Thereby, metallurgically bonded and dense wear and corrosion protection coatings are generated. This leads to significantly higher surface and deposition rates can be achieved in comparison to Laser Material Deposition (LMD), and heat-sensitive substrates can be coated. Moreover, in addition to this resource efficiency, the process is not only economically attractive but also sustainable. To reduce component weights as well as secondary energy consumption, aluminium has become an essential base material in most industrial sectors. Aluminium is not simple to process and the wear resistance is small due to the low hardness in comparison to widely used steels. Various technology solutions are currently being investigated for the coating of aluminium. The low melting temperature of aluminium (approx. 750 °C) poses a great challenge when coating with, for example, iron-based alloys. Another challenge for laser-based systems is the reflectance of aluminium in the wavelength range approx. between 1030-1070 nm of conventional laser beam sources. The high degree of reflection of aluminium is the reason why additive processing quiet challenging is. Therefore, for conventional laser-based processes, laser beam sources in other wavelength spectra, e.g. green or blue, are being developed to improve the processing of aluminium. Currently, commercially available multi-kW lasers in the visible light spectrum are still below the available power of IR beam sources. In the context of this study, the feasibility of coating aluminium using EHLA is investigated. A high power 8 kW IR disk laser of the TRUMPF company is used to determine the maximum possible deposition and surface rate.

Abstract:

Abstract Results are presented from two-phase flow wax deposition tests using a state-of-the-art, high pressure, multiphase flow test facility. Wax deposition was found to be flow pattern dependent and occurs only along the pipe wall in contact with the waxy crude oil. The deposition buildup trend at low mixture velocities is similar to that observed in laminar single-phase flow tests. The buildup trend at high mixture velocities is similar to that observed in turbulent single-phase flow tests. Thinner and harder deposits at the bottom than at the top of the pipe were observed in horizontal intermittent flow tests. Thicker and harder deposits were observed at low liquid superficial velocity than at high liquid superficial velocity annular flow tests. No wax deposition was observed along the upper portion of the pipe in stratified flow tests. A semi-empirical kinetic model tailored for the wax deposition tests predicted wax thickness with an acceptable accuracy, especially at high oil superficial velocity. Deposition rate reduction due to shear stripping and rate enhancement due to entrapment of oil and other mechanisms not accounted for by the classical Fick’s mass diffusion theory were incorporated through the use of dimensionless variables and empirical constants derived from the wax deposition data. The kinetic model, although semi-empirical, provides an insight for future model development.

Abstract:

Advancements in the establishment of the geological framework of the Sverdrup Basin resulting from the Geo-mapping for Energy and Minerals program can be grouped under the main topics of tectonostratigraphy, crosslinking of biostratigraphy and chronostratigraphy, integration of igneous records with newly refined stratigraphy, and effects of global climatic environments on hydrocarbon source rocks in geological time. New discoveries of volcanic ash beds throughout much of the Triassic stratigraphic section required new tectonic interpretations involving a magmatic arc northwest of the basin that was likely involved in the opening of the Amerasia Basin. Modern approaches to biostratigraphy calibrated by radiometric age dating of volcanic ash beds made global correlations to chronostratigraphic frameworks and tectonic models possible. Correlation of the stratigraphy and recent geochronology of the High Arctic large igneous province (HALIP) places the main pulse of mafic magmatism in a postrift setting. Finally, the depositional setting of source rocks in the Sverdrup Basin is explained in terms of oceanographic factors that are related to the global environment. All of these advancements, including hints of undefined and relatively young structural events, lead to the conclusion that the hydrocarbon potential of the Sverdrup Basin has not been fully tested by historical exploration drilling.
