Tello Guerra, Alexis (Date of defense: 2020-07-10)
The standard Fluid Structure Interaction coupling (velocity--pressure/displacement) is compared against two novel types of coupling, a Two Field coupling (velocity--pressure/displacement--pressure) and a Three Field coupling ...
García Alcaraz, María del Mar (Date of defense: 2016-03-04)
This thesis promotes an efficient use of shallow geothermal energy by means of an integrated management system to organize its exploitation. Shallow geothermal energy is a renewable resource based on thermal energy exchange ...
Borchini, Luca (Date of defense: 2020-12-17)
Nowadays, the main computational bottleneck in computer-assisted industrial design procedures is the necessity of testing multiple parameter settings for the same problem. Material properties, boundary conditions or ...
Monforte Vila, Lluís (Date of defense: 2018-11-05)
This thesis develops a numerical technique in which the Particle Finite Element method is applied to simulate solid intrusion problems in Geotechnical Engineering. The thesis describes the numerical development work that ...
Leon Medina, Jersson Xavier (Date of defense: 2023-10-06)
(English) In the last years, the condition monitoring of structures has evolved and improved using technologies such as artificial intelligence, sensor networks, and industry 4.0 because of the multiple advantages these ...
Alvarado Bueno, Mauricio (Date of defense: 2018-04-23)
Risk associated with landslides of natural or man-made origin depends on the prediction of the post-failure behaviour of the mobilized mass. Numerical models capable of integrating the landslide geometry and its evolution, ...
Salazar González, Fernando (Date of defense: 2017-02-23)
Dam behaviour is difficult to predict with high accuracy. Numerical models for structural calculation solve the equations of continuum mechanics, but are subject to considerable uncertainty as to the characterisation of ...
Codony, David (Date of defense: 2021-03-01)
This PhD thesis focuses on the development of mathematical and computational models for flexoelectricity, a relatively new electromechanical coupling that is present in any dielectric at the micron and sub-micron scales. ...
Marzeddu, Andrea (Date of defense: 2016-04-19)
The aim of this work is the study of laboratory effects on the measurement of wave impact induced loads on rigid maritime structures. A high number of experiments (more then 4000 using regular wave attacks) have been carried ...
Arias Araluce, Fausto Arturo (Date of defense: 2017-05-19)
Stroke is a major cause of death and disability in Spain and in the Western world. It is often caused by an accumulation of atherosclerotic plaques on the walls of carotid arteries. Carotid revascularization may be the ...
Ortiz Ruiz, Antonio (Date of defense: 2021-12-17)
Microalgae culture is currently receiving considerable attention for its potential in wastewater treatment and production of algal biomass from which high-value bioproducts and bioenergy can be obtained, as well as the ...
Larion, Ygee (Date of defense: 2022-02-01)
In a large number of geo-environmental applications, it is essential to model coupled processes that depend on several design parameters such as material properties and geometrical features. Thermo-hydro-mechanical (THM) ...
Puig Montellà, Eduard (Date of defense: 2019-07-16)
Numerical simulations at the pore scale are a way to study the behavior of multiphase flows encountered in many natural processes and industrial applications. In this work, liquid morphology and capillary action are examined ...
