Some inverse and control problems for fluids
(Université Blaise Pascal de Clermont-Ferrand, 2013)
This paper deals with some inverse and control problems for the Navier-Stokes and related systems. We will focus on some particular aspects that have recently led to interesting (theoretical and numerical) results: geometric ...

Weak time regularity and uniqueness for a Q-Tensor model
(Society for Industrial and Applied Mathematics, 2014)
The coupled Navier-Stokes and Q-Tensor system is one of the models used to describe the behavior of the nematic liquid crystals. The existence of weak solutions and a uniqueness criteria have been already studied (see [11] ...

On the very weak solution for the Oseen and Navier-Stokes equations
(American Institute of Mathematical Sciences, 2010-06)
We study the existence of very weak solutions regularity for the Stokes, Oseen and NavierStokes system when non-smooth Dirichlet boundary data for the velocity are considered in domains of class C1,1. In the Navier-Stokes ...

Efficient and scalable discretization of the Navier-Stokes equations with LPS modeling
(Elsevier, 2018-05-01)
In this work, we address the solution of the Navier–Stokes equations (NSE) by a Finite Element (FE) Local Projection Stabilization (LPS) method. The focus is on a LPS method that has one level, in the sense that it is ...

Stationary Stokes, Oseen and Navier-Stokes equations with singular data
(Springer, 2011)
The concept of very weak solution introduced by Giga [20] for the Stokes equations has been hardly studied in the last years for either the Navier-Stokes equations or the Navier-Stokes type equations. We treat the stationary ...

Motivation, analysis and control of the variable density Navier-Stokes equations
(AIMS, 2012-12)
Résultats d’unicité pour des problèmes pseudomonotones avec p > 2. Nous considérons un opérateur pseudomonotone du type −div(b(x, u)|∇ u| p−2∇ u), avec 1 <p< +∞ et b(x, s) une fonction Lipschitzienne en s qui vérifie 0 < ...

The Oseen and Navier-Stokes equations in a non-solenoidal framework
(Wiley, 2014-12-11)
The very weak solution for the Stokes, Oseen and Navier-Stokes equations has been studied by several authors in the last decades in domains of Rn, n ≥ 2. The authors studied the Oseen and Navier-Stokes problems assuming a ...

A survey on Navier-Stokes models with delays: Existence, uniqueness and asymptotic behavior of solutions
(2015)
In this survey paper we review several aspects related to Navier-Stokes models when some hereditary characteristics (constant, distributed or variable delay, memory, etc) appear in the formulation. First some results ...

On a double penalized smectic-A model
(American Institute of Mathematical Sciences, 2012-12)
In smectic-A liquid crystals a unity director vector n appear, modeling an average preferential direction of the molecules and also the normal vector of the layer configuration. In the E’s model [5] W. E. Nonlinear Continuum ...

Attractors for a Double Time-Delayed 2D-Navier-Stokes Model
(American Institute of Mathematical Sciences, 2014)
In this paper, a double time-delayed 2D-Navier-Stokes model is considered. It includes delays in the convective and the forcing terms. Existence and uniqueness results and suitable dynamical systems are established. We ...
