(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 ...
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 ...
The present thesis incorporates the CAD model into an adjoint-based optimization loop and uses it for the shape optimization of a 2D transonic turbine blade mid-section (profile). This is demonstrated by performing a single ...
The present thesis investigates how explicit filters can be useful in numerical simulations of turbulent, compressible flow with symmetry preserving discretizations. Such explicit filters provide stability to simulations ...
Without fluid turbulence, life might have rather different look. The atmosphere and oceans could nearly maintain a much larger temperature differences resulting in ultimate heating or cooling to the earth surface. The water ...
Una proporción muy importante del presupuesto energético total de los países europeos es destinado al consumo energético del sector de la edificación, tanto en el ámbito doméstico como terciario. Debido a que esta tendencia ...
(English) This thesis aims at developing a high-order finite volume method for solid dynamics on unstructured three-dimensional meshes. The adoption of high-order interpolation methods has a key importance in the efficient ...
The present thesis is devoted to the development and implementation of mathematical models and numerical methods in order to carry out computational simulations of complex heat and mass transfer phenomena. Several areas ...
The use of hybrid RANS-LES methods has become widespread during the last decade, as an interesting approach for covering the gap between RANS and LES turbulence models in terms of both computational resources and degree ...
The aim of this work is to study the thermal behavior and fluid-dynamic systems, vapor compression refrigeration and its components (heat exchangers, expansion devices, compressors, connecting pipes, pumps and pressure ...
Concentrated Solar Power (CSP) technologies are gaining increasing interest in electricity generation due to the good potential for scaling up renewable energy at the utility level. Parabolic trough solar collector (PTC) ...
The numerical simulation model presented is based on the integration of the fluid conservation equations (continuity, momentum and energy) in the whole compressor domain (compression chamber, valves, manifolds, mufflers, ...
The thesis topic is located in the domain of numerical simulation of laminar flames. The principal aim of the presented research is the study of numerical techniques for the multidimensional simulation of flames with low ...
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. ...
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 ...
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 ...
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 ...
Multiphase flows present a rich variety of physical instabilities, which may turn into a set of interesting techonological features. In the particular case of vertical fallings films, these features provide with short ...
