Pont Ribas, Arnau (Date of defense: 2018-02-23)
The solution of the human phonation problem applying computational mechanics is covered by several research branches, such as Computational Fluid Dynamics (CFD), biomechanics or acoustics, among others. In the present ...
Gutiérrez Álvarez, Enrique (Date of defense: 2018-07-17)
CFD techniques are important tools for the study of multiphase flows, because most of the physical phenomena of these flows often happen on space and time scales where experimental methodologies are impossible in practice. ...

L'aturada cardíaca és responsable d'un nombre significatiu de defuncions a Europa i als Estats Units, i la taxa de supervivència després d'una aturada cardíaca és baixa, per sota del 10 per cent. És important continuar ...
Barbu, L. G. (Lucia Gratiela) (Date of defense: 2016-02-01)
The present thesis aims at advancing an innovative computational methodology that simulates steel and composite material fracture under cyclic loading following a phenomenological approach, with calibration from both small ...
Arumugham Achari, Ajith Kumar (Date of defense: 2014-07-10)
Els electrosprays estan constituïts de microgotes amb alta càrrega elèctrica i en moviment sota l'acció de forces electrostàtiques. Les gotes es generen com a resultat de la ruptura d'un doll de líquid sotmès a un camp ...
Bartrons Casademont, Eduard (Date of defense: 2018-10-05)
The present thesis aims at developing a basis for the numerical simulation of the growth and densification of macroscopic frost sheets. Notwithstanding the fact that icing has still a long way to fully understand its ...
De Mier Torrecilla, Monica (Date of defense: 2010-06-29)
La presencia simultánea de múltiples fluidos con diferentes propiedades ocurre en numerosos problemas medioambientales, procesos industriales y situaciones de la vida diaria. Algunos ejemplos son la interacción fluido-combustible ...
Balcázar Arciniega, Néstor Vinicio (Date of defense: 2014-09-30)
This thesis aims at developing numerical methods based on level-set techniques suitable for the direct numerical simulation (DNS) of free surface and interfacial flows, in order to be used on basic research and industrial ...
Jofre Cruanyes, Lluís (Date of defense: 2014-07-25)
The present thesis aims at developing a basis for the numerical simulation of multiphase flows of immiscible fluids. This approach, although limited by the computational power of the present computers, is potentially very ...
Amani, Ahmad (Date of defense: 2019-07-24)
The complex nature of multiphase flows, particularly in the presence of non-Newtonian rheologies in the phases, limits the applicability of theoretical analysis of physical equations as well as setting up laboratory ...
Claramunt Altimira, Kilian (Date of defense: 2005-02-18)
Deep knowledge of combustion phenomena is of great scientific and technological interest. In fact, better design of combustion equipments (furnaces, boilers, engines, etc) can contribute both in the energy efficiency and ...
Novelli, Guillaume (Date of defense: 2011-11-24)
The pollution generated by accidental marine oil spills can cause persistent ecological disasters and lead to serious social and economical damages. Numerical simulations are a valuable tool to make proper decisions in ...
