Analysis of a semi-augmented mixed finite element method for double-diffusive natural convection in porous media
(2022-05-15)
In this paper we study a stationary double-diffusive natural convection problem in porous media given by a Navier-Stokes/Brinkman type system, for describing the velocity and the pressure, coupled to a vector advection-diffusion ...
Mixed methods for degenerate elliptic problems and application to fractional Laplacian
(EDP Sciences, 2021-02-26)
We analyze the approximation by mixed finite element methods of solutions of equations of the form −div (a∇u) = g, where the coefficient a = a(x) can degenerate going to zero or infinity. First, we extend the classic error ...
Thermodynamical consistency of quasiparticle model at finite baryon density
(Amer Physical Soc, 2019-07-24)
In this work, we revisit the thermodynamical self-consistency of the quasiparticle model with the finite baryon chemical potential adjusted to lattice QCD calculations. Here we investigate the possibility that the effective ...

A General-Purpose Element-Based Approach to Compute Dispersion Relations in Periodic Materials with Existing Finite Element Codes
(World Scientific Publishing Co. Pte LtdUniversidad EAFIT. Departamento de Ingeniería Mecánica, 2019-01-01)
The numerical determination of dispersion relations in periodic materials via the finite element method is a difficult task in most standard codes. Here, we propose a novel technique which allows the computation of these ...

Thermally developing forced convection of non-Newtonian fluids inside elliptical ducts
(2004-10-01)
Laminar-forced convection inside tubes of various cross-section shapes is of interest in the design of a low Reynolds number heat exchanger apparatus. Heat transfer to thermally developing, hydrodynamically developed forced ...

A 2-D model of Rayleigh instability in capillary tubes–surfactant effects
(Elsevier, 2004-05)
The Rayleigh instability of stagnant liquid films lining the interior of capillary tubes is analyzed with the aid of a 2-D free surface flow model; this axisymmetric model is previously validated using already published ...
