Least-squares driven stabilised finite element solution of advection-dominated flow problems
Tomás Chacón Rebollo, Daniel Franco Coronil
In this article, we address the solution of advection-dominated flow problems by stabilised methods, by means of least-squares computed stabilised coefficients. As main methodologi…
On a certified VMS-Smagorinsky Reduced Basis model with LPS pressure stabilisation
Tomás Chacón Rebollo, Enrique Delgado Ávila, Macarena Gómez Mármol
In this work we introduce a certified Reduced Basis VMS-Smagorinsky turbulence model with local projection stabilisation (LPS) on the pressure. We prove its stability for Taylor-Ho…
Certified Reduced Basis VMS-Smagorinsky model for natural convection flow in a cavity with variable height
Francesco Ballarin, Tomás Chacón Rebollo, Enrique Delgado Ávila +2
In this work we present a Reduced Basis VMS-Smagorinsky Boussinesq model, applied to natural convection problems in a variable height cavity, in which the buoyancy forces are invol…
VMS spectral solution of two-dimensional advection-diffusion problems with anisotropic velocity
Tomás Chacón Rebollo, Soledad Fernández-García, Macarena Gómez-Mármol
In this article, we extend the Variational Multi-scale method with spectral approximation of the sub-scales to two-dimensional advection-diffusion problems. The spectral VMS method…
A Petrov-Galerkin multilayer discretization to second order elliptic boundary value problems
Toms Chacón Rebollo, Daniel Franco Coronil, Frédéric Hecht
We study in this paper a multilayer discretization of second order elliptic problems, aimed at providing reliable multilayer discretizations of shallow fluid flow problems with dif…
Variational multi-scale spectral solution of convection-dominated parabolic problems
Tomás Chacón Rebollo, Soledad Fernández-García
In this work, we consider an extension to parabolic problems of the variational multiscale method with spectral approximation of the sub-scales. We first discretize in time using a…
