(English) Continuous enhancement in hardware technologies enables scientific computing to advance incessantly and reach further aims. Since the start of the global race for exascale high-performance computing (HPC), ...
The main objective of this thesis is the development of an adaptive mesh refinement (AMR) algorithm for computational fluid dynamics simulations using hexahedral and tetrahedral meshes. This numerical methodology is applied ...
Current refrigeration devices, based on vapour-compression cycles, employ refrigerants such as HFCs, which exhibit a global warming potential a thousand times higher than the one produced by CO2,. Furthermore, the increasing ...
Optical trapping and manipulation have emerged as powerful tools to investigate single microscopic objects in a controlled environment. Using the momentum carried by light, forces can be exerted to confine and manipulate ...
Environmental concerns regarding climate change and ozone depletion urge for a paradigm shift in the cooling production. The cooling demand exhibits an alarmingly increasing trend, thus its satisfaction in a sustainable ...
The high strength-weight ratio of composite materials have made them one of the best materials for the design of light-weight structures. However, its special complexity has made them not suitable for the design of structures ...
El desenvolupament de processos termoquímics destinats a la valorització de materials lignocel·lulòsics (gasificació i piròlisi, principalment), tant pel que fa al disseny de reactors com pel que fa a l'establiment de les ...
Fire is the most common phenomenon that characterizes major accidents that take place in both industrial establishments and in the transport of dangerous goods by road and rail. The formation of a fireball, with or without ...
CERN is presently constructing the LHC, which will produce collisions of 7 TeV protons in 4 interaction points at a design luminosity of 1034 cm-2 s-1. The radiation dose resulting from the operation at high luminosity ...
This thesis is dedicated to developing numerical methods to solve fluid-structure interaction (FSI) problems. FSI features in a vast range of physical systems and has a wide application in engineering. The work of this ...
This thesis presents the development of a parallel finite volume numerical method to analyse thermoelastic and hyperelastic materials and applied problems with mutual interaction between a fluid and a structure. The ...
This thesis presents a methodology for CFD-based multi-fidelity surrogate models for indoor environmental applications. The main idea of this work is to develop a model that has accuracy comparable to CFD simulations but ...
A conclusion that can be drawn from the historical safety analyses developed for tokamaks fusion reactors is that some of the major risks involve incidents in the vacuum vessel. In order to evaluate plasma evolution and ...
The main purpose of this thesis has been to contribute to the development of methodologies for wall modeling Large Eddy Simulations (LES) of wall-bounded flows, especially those at high Reynolds numbers. This flow configuration ...
Due to the continuously increasing energy demand and the environmental concerns about climate changes raised by international community, alternative energy resources have been put under intense investigation for the past ...
The advances in computing power have motivated the hope that computational methods can accelerate the pace of drug discovery pipelines. For this, fast, reliable and user-friendly tools are required. One of the fields that ...
Se ha estudiado la eficiencia de diferentes sistemas de iniciación química y térmica del curado de resinas de poliéster insaturado. Mediante calorimetría diferencial de barrido (DSC), se ha curado isotérmicamente y ...
En la investigació de la fusió termonuclear controlada per confinament magnètic es important conèixer el transport d'energia en els plasmes, doncs aquest transport és el que fa que es refredi més o menys ràpidament amb el ...
Synthetic jets are produced by the oscillatory movement of a membrane inside a cavity, causing fluid to enter and leave through a small orifice. This results in a net jet that is able to transfer kinetic energy and momentum ...
(English) This thesis focuses on modeling the circulation of liquid metal through the breeding blanket channels of a tokamak fusion reactor. Apart from extracting the heat produced by the nuclear reactions of the plasma, ...
