The main object of study of this thesis is the development of scalable and robust solvers based on domain decomposition (DD) methods for the linear systems arising from the finite element (FE) discretization of transient ...
(English) Turbidity currents in reservoirs are of strong scientific interest because they can be responsible for the contribution of large amounts of fine sediments that can cause early sediment filling. The case study ...
During the last years, the implementation of new Wastewater Treatment Plants has lead to a significant increase of sludge production. As a response, sludge valorisation in agriculture is the preferred option nowadays, ...
En esta tesis se presenta un modelo numérico para simular la fase de compactación de pulvimateriales y su implementación en ordenadores de cálculo paralelo, con el ánimo de facilitar y mejorar el diseño de los procesos de ...
(English) This doctoral thesis addresses one of the most significant challenges facing the Spanish administration: the efficient selection and management of public investments. To achieve this goal, the 'Public Investment ...
This thesis aims to propose and validate an innovative, fully open-source framework capable of performing multiscale analysis for the assessment of local wind flows within the urban fabric. Each part of the framework is ...
The Doñana wetlands, in Southwest Spain, undergo yearly cycles of inundation in fall and drying out during the spring season. As any wetland ecosystem, Doñana depends critically on its water resources. Important monitoring ...
Magnetohydrodynamics (MHD) is the physics branch that studies electrically conducting fluids under external magnetic fields. This thesis deals with the numerical approximation using stabilized finite element methods of two ...
This thesis presents the a stabilized projection-based Reduced Order Model (ROM) formulation in low speed fluid flows using a Variational Multi-Scale (VMS) approach. To develop this formulation we use a Finite Element (FE) ...
In order to be worldwide competitive, the automotive industry is constantly challenged to produce higher quality vehicles in the shortest time possible and with the minimum costs of production. Most of the problems with ...
The process of containerization and its continuous development involves changes and technological innovations in containerships and maritime container terminals. In the current era of "gigantism", despite existing fleet ...
This thesis presents some approaches for guided wave based stress monitoring as a part of Structural Health Monitoring (SHM). SHM systems include different levels, from damage detection to prognosis, however, this work is ...
Experimental study was conducted to analyze the physical flow turbulence and sediment distribution with submerged vane. The objectives behind the investigation were verified and compare results with the Odgaard theory, ...
The offshore wind sector has grown significantly during the last decades driven by the increasing demand for clean energy and to reach defined energy targets based on renewable energies. As the wind speeds tend to be faster ...
Los procesos termo-hidro-mecánicos relacionados con el almacenamiento geológico de carbono deben ser entendidos y cuantificados para demostrar a la opinión pública de que la inyección de dióxido de carbono (CO2) es segura. ...
This research project focuses on the analysis and prediction of flow structures and sediment transport process in open channels by using three-dimensional numerical models. The numerical study was performed using the ...
(English) Topology optimization of incompressible structures, in which the loads on the structure come from the stresses exerted by a surrounding fluid, is a highly complex problem. This work presents a compilation of the ...
Recent developments of high performance computing capabilities allow solving modern science problems employing sophisticated computational techniques. However, it is necessary to ensure the efficiency of state of the art ...
This thesis develops a numerical tool (the Virtual Wind Tunnel, VWT) for the resolution of problems involving fluid flow around structures. Due to the limitations that traditional methods may have in this context, the VWT ...
This thesis deals with uncertainty in radar-based precipitation estimation and nowcasting in two ways: its quantification in a probabilistic manner, and its reduction in the precipitation estimates. A straightforward way ...
