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 ...
La evaluación preliminar de los resultados de la Reforma Ferroviaria Europea muestra la lentitud de su implementación y la existencia de insuficiencias en el nivel de competencia introducido en el mercado y en la consecución ...
Actualmente hay diversas corrientes investigadoras que han profundizado en el estudio del comportamiento mecánico de los materiales, dejando un apreciable cúmulo de experiencias aprovechables. No obstante, se encuentran ...
This paper presents a numerical approach for the simulation of reinforced concrete pieces in three dimensions, using embedded discontinuity elements, based on the strong discontinuity approach. In turn, this work is divided ...
(English) Induced seismicity due to hydraulic stimulation and circulation is a hurdle for the development of Enhanced Geothermal Systems (EGS). The monitored seismicity has occasionally reached magnitudes large enough to ...
(English) This thesis covers the development of large-scale numerical methods for the simulations of partial differential equations on arbitrarily complex geometries. The target application of this thesis is the structural ...
(English) In order to converge towards Vision Zero concept in road safety, traffic crashes need great study and analysis. This thesis is aimed at this goal, applied to the urban and metropolitan environment of Barcelona. ...
A pesar de que la utilización del método de los elementos finitos está muy extendida, es difícil determinar el nivel de precisión de los resultados obtenidos. Para ello es necesario utilizar alguno de los mallados estimadores ...
The present work is a compilation of the research produced in the field of wave propagation modeling. It contains in-depth analysis of stability, convergence, dispersion and dissipation of spatial, temporal and spatial-temporal ...
This thesis describes the extension of the Finite Element Method with zero-thickness interface elements (FEM+z) to 3D, large and complex problems in geomaterials, with special interest in petroleum geomechanics. This general ...
