Mixed 3D-2D asymptotics for the weak and strong solutions of the rotating magnetohydrodynamic system
Frédéric Charve, Van-Sang Ngo
In this article, we consider the 3D-rotating magnetohydrodynamic (MHD) system when the initial velocity and magnetic field both feature some 2D-part (i.-e. depending only on the ho…
Determination of time dependent source terms for Stokes systems in unbounded domains
Adel Blouza, Léo Glangetas, Yavar Kian +1
This article is devoted to the analysis of inverse source problems for Stokes systems in unbounded domains where the corresponding velocity flow is observed on a surface. Our main…
Hydrostatic limit of the Navier-Stokes-alpha model
Léo Glangetas, Van-Sang Ngo, El Mehdi Said
In this paper we study the hydrostatic limit of the Navier-Stokes-alpha model in a very thin striped domain. We derive some Prandtl-type limit equations for this model and we prove…
Hydrostatic approximation of the 2D primitive equations in a thin strip
Nacer Aarach, Van-Sang Ngo
We prove the global wellposedness of the 2D non-rotating primitive equations with no-slip boundary conditions in a thin strip of width $\eps$ for small data which are analytic in t…
Approximate controllability of second grade fluids
Van-Sang Ngo, Geneviève Raugel
This paper deals with the controllability of the second grade fluids, a class of non-Newtonian of differentiel type, on a two-dimensional torus. Using the method of Agrachev-Sarych…
On the influence of gravity on density-dependent incompressible periodic fluids
Van-Sang Ngo, Stefano Scrobogna
The present work is devoted to the analysis of density-dependent, incompressible fluids in a 3D torus, when the Froude number goes to zero. We consider the very gener…
Boundary Layer Analysis for the Fast Horizontal Rotating Fluids
Wei-Xi Li, Van-Sang Ngo, Chao-Jiang Xu
It is well known that, for fast rotating fluids with the axis of rotation being perpendicular to the boundary, the boundary layer is of Ekman-type, described by a linear ODE system…
Dispersive effects of weakly compressible and fast rotating inviscid fluids
Van-Sang Ngo, Stefano Scrobogna
We consider a system describing the motion of an isentropic, inviscid, weakly com-pressible, fast rotating fluid in the whole space R^3 , with initial data belonging to H^s(R^3) ,…
A global existence result for the anisotropic magnetohydrodynamical systems
Van-Sang Ngo
We study an anisotropic system arising in magnetohydrodynamics (MHD) in the whole space R^3 , in the case where there are no diffusivity in the vertical direction and only a small…
