Descriptif

The objective is to present the fluid approach of the generalized Magnetohydrodynamics (MHD) theory in which the corpuscular aspect (electrons, ions) is no longer essential to describe the linear and nonlinear physical processes in magnetized plasmas. Four main parts will be discussed: (I) Theoretical foundations of MHD, (II) Invariants and equilibria, (III) Instabilities and magnetic containment, (IV) MHD turbulence. The articulation between these parts will be facilitated by examples from astrophysical plasmas and magnetic thermonuclear fusion.
