Повний текст джерелаIn this thesis we study the global behavior of solutions of the energy-criticalfocusing nonlinear wave equation, with a special emphasis on the description of the dynamics in the energy space. We develop a new approach, based on the energy method, to constructing unstable type II blow-up solutions. Next, we give the first example of a radial two-bubble solution of the energy-critical wave equation. By implementing this construction in the case of the equivariant wave map equation, we obtain bubble-antibubble solutions in equivariance classes k > 2. We also study the relationship between the speed of a type II blow-up and the weak limit of the solution at the blow-up time. Finally, we prove that there are no pure radial two-bubbles with opposite signs for the energy-critical wave equation

over one- and two-dimensional bathymetries. In one-dimensional case, the nonlinear equations are solved for a plane beach using the hodograph transformation with eigenfunction expansion or integral transform methods under different initial conditions, i.e., earthquake-generated waves, wind set-down relaxation, and landslide-generated waves. In two-dimensional case, the linear shallow-water wave equation is solved for a flat ocean bottom for initial waves having finite-crest length. Analytical verification of source focusing is presented. The role of focusing in unexpectedly high tsunami runup observations for the 17 July 1998 Papua New Guinea and 17 July 2006 Java Island, Indonesia tsunamis are investigated. Analytical models developed here can serve as benchmark solutions for numerical studies.

Повний текст джерелаEtt nytt koncept för att utvinna förnyelsebar energi har framtagits på KTH Elkraftteknik, denna gång handlar det om vågkraft. Till skillnad från flera andra vågkraftverk så öppnar detta koncepts nyframtagna generator upp för möjligheten att vara verksamt även vid låga hastigheter samtidigt som det bibehåller hög krafttäthet samt verkningsgrad. Denna lösning av generatorn är i behov av att tätas då dess ingående komponenter inte tål den omgivande havsmiljön, detta är därför syftet med projektet som genomförts. Flertalet problem existerar med de lösningar som för nuvarande finns att tillgå, varför det finns behov av att ta fram en skräddarsydd tätningslösning till detta koncept. Dessa problem är exempelvis läckage och utmattningsbrott vilka leder till att livslängden hos tätningarna blir oacceptabelt kort. De frågeställningar vilka i rapporten och projektet behandlas är ifall det finns några belastningar verkande på tätningen som är specifikt kritiska, ifall det finns något enkelt sätt att reducera just dessa, ifall det finns några lösningar som är tätare än de som finns att tillgå idag (som också har godkända egenskaper gällande hållfasthet och livslängd till följd av de krav som ställs på dem), ifall dessa lösningar skulle vara applicerbara i alla hav och ifall dessa lösningar är ekonomiskt tillämpbara. För att besvara detta har flertalet konceptgenereringar utförts med hjälp av brainstorming där potentiella lösningar utvärderats baserat på en omfattande informationssökning, för att till sist komma fram till och skissera upp de mest lovande slutkoncepten. Dessa modellerades därefter upp med hjälp av 3D-modelleringsprogrammet Solid Edge för att slutligen analyseras med programvaran Ansys. Resultaten och slutsatserna från både informationssökningen och de utförliga analyserna var att de kritiska belastningarna är de spänningar vilka uppstår till följd av kompression, expansion och böjning av bojen, vilka kan reduceras genom att skapa en inre struktur i tätningen som leder till att belastningarna sker mer jämnt. Det finns även tätningslösningar vilka är helt täta då de inkapslar den del av vågkraftskonceptet som behöver tätas, så kallade damasklösningar. Dessa lösningar är dessutom applicerbara i alla hav både ur ett perspektiv gällande material men också ett dimensioneringsmässigt sådant, där möjligheten finns att justera tätningens längd vid tillverkningen utefter den varierande våghöjden där denna ska appliceras. Gällande den sista frågan vilken behandlar den ekonomiska tillämpbarheten kunde inga tillräckligt träffsäkra resultat genereras och därav inga slutsatser dras.
Brouzet, Christophe. "Internal wave attractors : from geometrical focusing to non-linear energy cascade and mixing." Thesis, Lyon, 2016. http://www.theses.fr/2016LYSEN012/document.
Повний текст джерелаA question of paramount importance in the dynamics of oceans is related to the energy cascade from large to small scales and its contribution to mixing. Internal wave attractors may be one of the possible mechanisms responsible for such a cascade. In this manuscript, we study experimentally internal wave attractors in a trapezoidal test tank filled with linearly stratified fluid. In such a geometry, the waves can form closed loops called attractors. We show that the attractor formation is purely linear: small scales are thus created by wave focusing. The attractor characteristics are found to only depend on the trapezoidal geometry of the tank. At the ocean scale, we show that attractors are very likely to be unstable. Indeed, internal wave attractors are prone to a triadic resonance instability, which transfers energy from the attractor to a pair of secondary waves. This instability and its main characteristics are described as a function of the geometry of the basin. For long-term experiments, the instability produces several pairs of secondary waves, creating a cascade of triadic interactions and transferring energy from large-scale monochromatic input to multi-scale internal-wave motion. We reveal, for the first time, experimental convincing signatures of internal wave turbulence. Beyond this cascade, we have a mixing regime, which appears to be independent of the trapezoidal geometry and, thus, universal. This manuscript is completed by a study on added mass and wave damping coefficient of bodies oscillating horizontally in a stratified fluid, with applications to tidal conversion

Acoustic Non-Destructive Testing (NDT) has a long history of applications in fatigue monitoring, fault testing, and more recently production control. A very large family of manufactured and raw materials consist of thin layers. Some examples include rolled aluminum, window glass, plywood, automobile bodies, plane wings, silicon wafers, bridge support beams, and paper. These layers can be viewed and modeled as acoustic waveguides. This thesis will present the framework in which to analyze such layers. To this end, analytic solutions to the plane wave displacement and stress fields in a single layer monoclinic material will be presented The propagation, frequency, and dispersive characteristics of transmitted signals can be analyzed to determine various elastic properties of the layer or to identify faults. Wavelet (time-frequency), Fourier (frequency), and signal matching (time) techniques will be developed to analyze and extract features and properties of signals. Several experimental examples will be presented.
