PIV mapping of pressure and velocity fields in the plane magnetohydrodynamic Couette flow

Brahim Moudjed, Alban Pothérat, Martin Holdsworth

We present the first simultaneous mapping of two-dimensional, time-dependent velocity and pressure fields in a plane Couette flow pervaded by a transverse magnetic field. While ele…

An effective two-dimensional model for MHD flows with transverse magnetic field

Alban Pothérat, Joël Sommeria, René Moreau

This paper presents a model for quasi two-dimensional MHD flows between two planes with small magnetic Reynolds number and constant transverse magnetic field orthogonal to the plan…

2D models for MHD flows

Alban Pothérat, Joël Sommeria, René Moreau

A new model is proposed for low MHD flows which remain turbulent even in the presence of a magnetic field. These flows minimize the Joule dissipation because of their tendency…

Numerical simulations of an effective two-dimensional model for flows with a transverse magnetic field

Alban Pothérat, Joël Sommeria, René Moreau

This paper presents simulations of the 2d model developed by Pothérat at al (\emph{J. Fluid Mech}, 2000) for MHD flows between two planes with a strong transverse homogeneous and s…

Effective boundary conditions for magnetohydrodynamic flows with thin Hartmann layers

Alban Pothérat, Joël Sommeria, René Moreau

Here we build some effective boundary conditions to be used in numerical calculations in order to avoid the thin meshing usually required in problems involving Hartmann layers near…

Small scales and anisotropy in low magnetohydrodynamic turbulence

Alban Pothérat, Thierry Alboussière

In this paper, we derive estimates for size of the small scales and the attractor dimension in low magnetohydrodynamic turbulence by deriving a rigorous upper bound of the dim…
