Analysis of numerical stability of algebraic oceanic turbulent mixing layer models
(Elsevier, 2014-05-10)
In this paper, we study the stability of oceanic turbulent mixing layers by the finite element method with respect to perturbations of the data. We prove that the equilibria states depend continuously on the data, and ...

Assessment of self-adapting local projection-based solvers for laminar and turbulent industrial flows
(Springer, 2018-06)
In this work, we study the performance of some local projection-based solvers in the Large Eddy Simulation (LES) of laminar and turbulent flows governed by the incompressible Navier–Stokes Equations (NSE). On one side, we ...

A High-Order Local Projection Stabilization Method for Natural Convection Problems
(Springer, 2017-06-05)
In this paper, we propose a local projection stabilization (LPS) finite element method applied to numerically solve natural convection problems. This method replaces the projection-stabilized structure of standard LPS ...

On the existence and asymptotic stability of solutions for unsteady mixing-layer models
(AIMS, 2014-02-15)
We introduce in this paper some elements for the mathematical analysis of turbulence models for oceanic surface mixing layers. We consider Richardson-number based vertical eddy diffusion models. We prove the existence ...

Numerical modelling of turbulence by Richardson number-based and VMS models / Modelado numérico de la turbulencia mediante modelos de Richardson y de Multiescala Variacional
(2014-04-02)
La presente tesis aborda el modelado numérico de la turbulencia mediante modelos de Richardson y de Multiescala Variacional (VMS). En la primera parte, nos centramos en los modelos basados en el número de Richardson, que ...

Numerical investigation of algebraic oceanic turbulent mixing-layer models
(Copernicus Publications, 2013-11-06)
In this paper we investigate the finite-time and asymptotic behaviour of algebraic turbulent mixing-layer models by numerical simulation. We compare the performances given by three different settings of the eddy viscosity. ...

Numerical analysis of a finite element projection-based VMS turbulence model with wall laws
(Elsevier, 2014-11-13)
This paper deals with the numerical analysis of a finite element projection-based VMS turbulence model that includes general non-linear wall laws. Only a single mesh and interpolation operators on a virtual coarser mesh ...
