Classical and recurrent nova models
(2011)
Comunicació de congrés
Accés obertRemarkable progress in the understanding of nova outbursts has been achieved through combined efforts in photometry, spectroscopy and numerical simulations. According to the thermonuclear runaway model, novae are powered ... -
Confined rotating convection in water-ethanol mixtures
(Universitat Politècnica de Catalunya, 2019-10-15)
Treball Final de Grau
Accés obertFlows driven by temperature gradients in the presence of a gravity field have interest in geophysical flows and in many engineering applications (heat transfer, crystal growth, storage tanks, etc ). Special attention ... -
Critical torsional modes of convection in rotating fluid spheres at high Taylor numbers
(2016-02-15)
Article
Accés obertA numerical study of the onset of convection in rotating internally heated self-gravitating fluid spheres is presented. The exploration of the stability of the conduction state versus the Taylor and Prandtl numbers supplies ... -
Dissolution patterns and mixing dynamics in unstable reactive flow
(2015-08-16)
Article
Accés obertWe study the fundamental problem of mixing and chemical reactions under a Rayleigh-Taylor-type hydrodynamic instability in a miscible two-fluid system. The dense fluid mixture, which is generated at the fluid-fluid interface, ... -
"Mesh-free methods and finite elements: friend or foe?"
(Universitat Politècnica de Catalunya, 2001-11-16)
Tesi
Accés obertThis thesis is devoted to the numerical analysis of mesh-free methods and, in particular, to the study of the possible advantages of the EFG (Element Free Galerkin) mesh-free method against the well-known FE (Finite Element) ... -
Study for the computational resolution of conservation equations of mass, momentum and energy
(Universitat Politècnica de Catalunya, 2022-06)
Treball Final de Grau
Accés obertThe main objective of that project is the development and posterior verification of C++ codes able to solve the incompressible Navier-Stokes equations. Nonetheless, before attaching the mainconcerned objective other ... -
Turbulent convection by thermoelectricity in a cooling-heating didactive device
(Moscow Institute of Physics and Technology (MIPT), 2017-04)
Article
Accés obertLocal Diffusion and the topological structure of vorticity and velocity fields is measured in the transition from a homogeneous linearly stratified fluid to a cellular or layered structure by means of convective cooling ...
