Radial collocation methods for the onset of convection in rotating spheres
(2016-03-01)
Article
Accés obertThe viability of using collocation methods in radius and spherical harmonics in the angular variables to calculate convective flows in full spherical geometry is examined. As a test problem the stability of the conductive ... -
Stability analysis for the onset of convection in rotating fluid binary mixtures in spherical shells
(2011)
Text en actes de congrés
Accés obertThe stability analysis of the basic conductive state of a rotating binary mixture of two fluids bounded by spherical shells is studied. The Boussinesq approximation of the mass conservation, Navier-Stokes, energy and ... -
Stationary flows and periodic dynamics of binary mixtures in tall laterally heated slots
(Springer, 2018-07-05)
Capítol de llibre
Accés restringit per política de l'editorialThe steady and oscillatory dynamics of binary fluids contained in slots heated by the side is studied by using continuation methods, and stability analysis. The bifurcation points on the branches of solutions are determined ... -

Thermal convection in rotating spherical geometry: a numerical overview of the transitions from periodic axisymmetric to temporally complex three-dimensional flows
(American Institute of Physics (AIP), 2022-12-16)
Article
Accés obertThe aim of this work is to elucidate the type of transitions that take place when the periodic axisymmetric flows, which can set up at the onset of thermal convection in rotating fluid spheres, lose stability and to study ... -
Three-dimensional quasiperiodic torsional flows in rotating spherical fluids at very low Prandtl numbers
(2021-11-04)
Article
Accés obertThe aim of this study is to determine through numerical simulations the extent and robustness of the three-dimensional torsional dynamics of the thermal convection in rotating spherical fluids at very low Prandtl numbers. ... -
Torsional solutions of convection in rotating fluid spheres
(2019-01-25)
Article
Accés obertA numerical study of the nonlinear torsional solutions of convection in rotating, internally heated, self-gravitating fluid spheres is presented. Their dependence on the Rayleigh number has been found for two pairs of Ekman ... -
Two computational approaches for the simulation of fluid problems in rotating spherical shells
(2014)
Article
Accés obertMany geophysical and astrophysical phenomena such as magnetic fields generation, or the differential rotation observed in the atmospheres of the major planets are studied by means of numerical simulations of the Navier-Stokes ... -
