MHD, Plasmas & Superfluids

MHD, Plasmas & Superfluids

The simplest model of both plasma dynamics and conducting fluids is the magnetohydrodynamic (MHD) description. MHD is used in our team to investigate, numerically and theoretically, the behaviour of fusion plasmas, rotating conducting fluids and magnetic-field amplification (dynamo-effect).

Stabilité des écoulements de contre-courant d’Hélium superfluide : applications à la réfrigération cryogénique

La conductivité thermique exceptionnelle de l’hélium liquide superfluide (en dessous de 2,17 K) permet un refroidissement efficace avec de très faibles gradients thermiques. Cette particularité est (...)

The von Kármán - Plasma experiment

We investigate the dynamics of a von Karman plasma (VKP) flow, a flow in a cylindrical cavity between rotating discs. In close collaboration with the team of Nicolas Plihon (Physics Lab, (...)

Anisotropic dynamics of conducting fluids with and without rotation

Anisotropic dynamics of conducting fluids with and without rotation

Turbulence, waves and instabilities in conducting fluids are investigated using high resolution numerical simulations and theoretical analysis. A particular emphasis is put on the anisotropic (...)

Numerical investigation of velocity fields in fusion plasmas

Numerical investigation of velocity fields in fusion plasmas

Most of the existing magnetically confined fusion plasmas move and are turbulent, which is sometimes quite a problem. Indeed, in order to get a nuclear fusion reaction started, and to keep it (...)
