Experimental and numerical analyses of flow-limited chemical reactions in laminar and turbulent regimes
Aquesta tesis es divideix en tres blocs on s’analitza l’efecte de diferents règims de flux en reaccions químiques. El primer bloc analitza una base de dades obtinguda a partir de simulació numèrica d’un flux reactiu i ...
Experimental and numerical analysis of the unsaturated soil shrinkage and swelling behaviour under different compaction conditions
(English) The thesis presents part of an ongoing nvestigation on the Thermo-Hydro-Mechanical (THM) behaviour and cracking of deformable unsaturated soils undergoing cycles of drying and wetting. An experimental approach ...
Experimental and Numerical investigation of flow in a lid-driven cylindrical cavity
En aquest treball, s'investiga el flux en una cavitat cilíndrica amb una tapa giratòria utilitzant eines experimentals i computacionals. La velocitat de rotació de la tapa es manté constant amb el temps o es varia periòdicament ...
Experimental and numerical investigation of the flow in a toroidal cavity
The shear-driven incompressible flow in a toroidal cavity of square crosssection<br/>(DxD) and radius of curvature Rc has been studied both experimentally and<br/>numerically. The flow has been realized in two toroidal ...
Experimental and numerical modelling of CO2 behaviour in the soil-atmosphere interface : implications far risk assessment of carbon capture storage projects
CO2 geological storage is considered one of the options technologically viable in order to decrease the industrial emissions of this gas species that strongly contribute to the greenhouse effect in the atmosphere (IPCC, ...
Experimental and numerical study of chemo-hydro-mechanical effects of CO2 injection on permeable limestone
[eng] Carbon capture and storage (CCS) in saline aquifers is a proven technology aimed at reducing atmospheric CO2 emissions and mitigating the climate change crisis. CO2 injection acidifies the formation water inducing ...
Experimental and numerical study of the effect of stress on ASR expansions in concrete
This thesis aims at deepening in the understanding of the mechanisms by which the stress state affects the development of concrete expansions and cracking due to the Alkali-Silica Reaction (ASR). With this purpose, a ...
Experimental and numerical study of the structural effects of steel corrosion in continuous RC beams
Many reinforced concrete structures suffer damage due to aging and due to the environmental agressivity, thus affecting their serviceability performance and safety. Structural evaluation of a deteriorated structure is ...
Experimental and numerical study of the symbolic dynamics of modulated semiconductor lasers with optical feedback
The goal of this thesis is to investigate the influence of current modulation in the dynamics of the low-frequency fluctuations (LFF) regime induced by optical feedback in semiconductor lasers. In this regime the laser ...
Experimental and theoretical analysis of cracking in drying soils
The thesis focuses on the experimental and theoretical aspects of the process of cracking in drying soils. The results and conclusions were drawn from an exhaustive experimental campaign characterised by innovative ...
Experimental and theoretical analysis of flow and sediment transport in 90-degree fluvial diversions.
Fluvial bifurcations are systems that have a great influence on human society. Their formation and evolution can affect to activities as agriculture or industry and a good knowledge of the mechanisms that affect the processes ...
Experimental and theoretical study of solubility of new absorbents in natural refrigerants
En aquesta tesi s'ha realitzat un estudi experimental i teòric de la solubilitat de nous absorbents en refrigerants naturals. El mesurament de la temperatura de solubilitat dels nous fluids de treball NH3/LiNO3, NH3/NaSCN ...
An experimental and theoretical view of autocatalytic colloids interacting with interfases
This thesis contains my doctoral research in condensed soft matter physics prepared at the University of Barcelona. It covers the interaction of active Janus particles with liquid-liquid and liquid-solid interfaces, both ...
An experimental approach to define a new perimortem blunt force trauma bone pattern presented in a human model
INTRODUCCIÓ - Determinar la cronologia d'una fractura òssia segueix sent una de les tasques més difícils en antropologia forense. En la literatura, es poden trobar diferents descripcions i abordatges per diferenciar entre ...
Experimental Approaches for Pulp Tissue Regeneration
The aim of this PhD thesis was to study experimental approaches for revitalization of necrotic teeth. Revitalization, also known as regenerative endodontic procedures (REPs), is a relatively new treatment for necrotic teeth ...
Experimental basis for the control of plant diseases caused by Xylella fastidiosa using synthetic antimicrobial peptides
Xylella fastidiosa is one of the most damaging phytopathogenic bacteria in the world, causing a variety of diseases with a major economic impact on agriculture and the environment. Until now, no therapeutic solution has ...
Experimental characterization and diagonosis tools for proton exchange membrane fuel cells
A fuel cell is a device that gives electric power directly from electrochemical reduction and oxidation reactions. PEM fuel cells present some properties that make them appropriate for portable and transport applications: ...
