A locally extended finite element method for the simulation of multi-fluid flows using the Particle Level Set method
(2015-09)
Article
Accés obertThe simulation of immiscible two-phase flows on Eulerian meshes requires the use of special techniques to guarantee a sharp definition of the evolving fluid interface. This work describes the combination of two distinct ... -
Analysis of an unconditionally convergent stabilized finite element formulation for incompressible magnetohydrodynamics
(2015-11)
Article
Accés obertIn this work, we analyze a recently proposed stabilized finite element formulation for the approximation of the resistive magnetohydrodynamics equations. The novelty of this formulation with respect to existing ones is the ... -
Approximation of the two-fluid flow problem for viscoelastic fluids using the level set method and pressure enriched finite element shape functions
(2015-11-01)
Article
Accés obertThe numerical simulation of complex flows has been a subject of intense research in the last years with important industrial applications in many fields. In this paper we present a finite element method to solve the two ... -
Auto-Backlund transformations and special integrals for differential-delay Painlevé hierarchies
(2014-10-01)
Article
Accés restringit per política de l'editorialThe six Painleve equations have attracted much interest over the last thirty years or so. More recently many authors have begun to explore properties of higher-order versions of both these equations and their discrete ... -
Discrete Serrin's problem
(Elsevier, 2015-03-01)
Article
Accés obertWe consider here the discrete analogue of Serrin's problem: if the equilibrium measure of a network with boundary satisfies that its normal derivative is constant, what can be said about the structure of the network and ... -
Secondary flows in a laterally heated horizontal cylinder
(2014-01-01)
Article
Accés obertIn this paper we study the problem of thermal convection in a laterally heated, finite, horizontal cylinder. We consider cylinders of moderate aspect ratio (height/diameter approximate to 2) containing a small Prandtl ... -
Shear design of reinforced concrete beams with FRP longitudinal and transverse reinforcement
(Elsevier, 2015-06)
Article
Accés obertThe shear resisting mechanisms of reinforced concrete (RC) beams with longitudinal and transverse FRP reinforcement can be affected by the mechanical properties of the FRP rebars. This paper presents a mechanical model for ... -
Stress-accurate Mixed FEM for soil failure under shallow foundations involving strain localization in plasticity
(2015-03)
Article
Accés obertThe development of slip lines, due to strain localization, is a common cause for failure of soil in many circumstances investigated in geotechnical engineering. Through the use of numerical methods - like finite elements ...
