A comparison of three turbulence models with an application to the West Pacific Warm Pool
Bennis, Anne-Claire; Gómez Mármol, María Macarena; Lewandowski, Roger; Chacón Rebollo, Tomás; Brossier, Françoise (2007)In this work, we compare three turbulence models used to parameterize the oceanic boundary layer. These three models depend ...

A model for two coupled turbulent fluids. Part II: numerical analysis of a spectral discretization
Bernardi, Christine; Chacón Rebollo, Tomás; Lewandowski, Roger; Murat, François (Society for Industrial and Applied Mathematics, 2002)We consider a system of equations that models the stationary flow of two immiscible turbulentfluids on adjacentsubdomains. ...

A variational finite element model for Large-Eddy simulations of turbulent flows
Chacón Rebollo, Tomás; Lewandowski, Roger (Springer, 2013-09)We introduce a new Large Eddy Simulation model in a channel, based on the projection on finite element spaces as filtering ...

Stability of some turbulent vertical models for the ocean mixing boundary layer
Bennis, Anne-Claire; Chacón Rebollo, Tomás; Gómez Mármol, María Macarena; Lewandowski, Roger (Elsevier, 2008-02)We consider four turbulent models to simulate the boundary mixing layer of the ocean. We show the existence of solutions to these models in the steady-state case then we study the mathematical stability of these solutions.
