A Variational Finite Element Model for Large-Eddy Simulations of Turbulent Flows
Tomas Chacon Rebello, Roger Lewandowski
We introduce a new Large Eddy Simulation model in a channel, based on the projection on finite element spaces as filtering operation in its variational form, for a given triangulat…
Modeling error in Approximate Deconvolution Models
Adrian Dunca, Roger Lewandowski
We investigate the assymptotic behaviour of the modeling error in approximate deconvolution model in the 3D periodic case, when the order of deconvolution goes to . We…
Attractors for a deconvolution model of turbulence
Roger Lewandowski, Yves Preaux
We consider a deconvolution model for 3D periodic flows. We show the existence of a global attractor for the model.
A high accuracy Leray-deconvolution model of turbulence and its limiting behavior
William Layton, Roger Lewandowski
In 1934 J. Leray proposed a regularization of the Navier-Stokes equations whose limits were weak solutions of the NSE. Recently, a modification of the Leray model, called the Leray…
A comparison of three turbulence models with an application to the West Pacific Warm Pool
Anne-Claire Bennis, Macarena Gomez Marmol, Roger Lewandowski +2
In this work, we compare three turbulence models used to parameterize the oceanic boundary layer. These three models depend on the bulk Richardson number, which is coherent with th…
Numerical simulation of water flow around a rigid fishing net
Roger Lewandowski, Géraldine Pichot
This paper is devoted to the simulation of the flow around and inside a rigid axisymmetric net. We describe first how experimental data have been obtained. We show in detail the mo…
