      Flows 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 

      Sánchez Umbría, Juan; García González, Fernando; Net Marcé, Marta (2016-02-15)
      Article
      Accés obert
      A 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 

      Hidalgo, Juan J.; Dentz, Marco; Cabeza Diaz de Ceiro, Yoar; Carrera Ramírez, Jesús (2015-08-16)
      Article
      Accés obert
      We 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?" 

      Fernàndez Méndez, Sònia (Universitat Politècnica de Catalunya, 2001-11-16)
      Tesi
      Accés obert
      This 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 

      Navas González, Rubén (Universitat Politècnica de Catalunya, 2022-06)
      Treball Final de Grau
      Accés obert
      The 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 

      Redondo Apraiz, José Manuel; Tellez Alvarez, Jackson David; Sanchez, Jesus Mary (Moscow Institute of Physics and Technology (MIPT), 2017-04)
      Article
      Accés obert
      Local 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 ...
