Continuous boundary condition at the interface for two coupled fluids
François Legeais, Roger Lewandowski
We consider two laminar incompressible flows coupled by the continuous law at a fixed interface. We approach the system by one that satisfies a friction Navier law, and we show tha…
On the existence of weak solutions for a family of unsteady rotational Smagorinsky models
Luigi C. Berselli, Alex Kaltenbach, Roger Lewandowski +1
In this paper we show that the rotational Smagorinsky model for turbulent flows, can be put, for a wide range of parameters in the setting of Bochner pseudo-monotone evolution equa…
Turbulent flows as generalized Kelvin-Voigt materials: modeling and analysis
Cherif Amrouche, Luigi C. Berselli, Roger Lewandowski +1
We model a 3D turbulent fluid, evolving toward a statistical equilibrium, by adding to the equations for the mean field a term like . This is…
Long-Time Reynolds Averaging of Reduced Order Models for Fluid Flows: Preliminary Results
Luigi C. Berselli, Traian Iliescu, Birgul Koc +1
We perform a theoretical and numerical investigation of the time-average of energy exchange among modes of Reduced Order Models (ROMs) of fluid flows. We are interested in the stat…
A model under location uncertainty to predict the mean velocity in wall bounded flows
Benoit Pinier, Etienne Mémin, Sylvain Laizet +1
To date no satisfying model exists to explain the mean velocity profile within the whole turbulent layer of canonical wall bounded flows. We propose a modification of the velocity…
Deterministics descriptions of the turbulence in the Navier-Stokes equations
Oscar Jarrin, Isabelle Gallagher, Lorenzo Brandolese +3
This PhD thesis is devoted to deterministic study of the turbulence in the Navier- Stokes equations. The thesis is divided in four independent chapters.The first chapter involves a…
