 Magnetohydrodynamic turbulence

Magnetohydrodynamic turbulence is irregular nonlinear motion of an electrically conducting fluid coupled to a magnetic field. Alfvén waves and magnetosonic waves give propagation times in addition to the nonlinear mixing time. A strong guide field distinguishes directions parallel and perpendicular to it, so the resulting cascades need not be isotropic.

Magnetohydrodynamic (MHD) turbulence is a complex field of study that combines aspects of fluid dynamics and magnetohydrodynamics, which is the behavior of electrically conducting fluids in the presence of a magnetic field. MHD turbulence is particularly relevant in astrophysical contexts, such as in the behavior of plasmas in stars, galaxies, and interstellar space, as well as in industrial processes involving liquid metals and other conducting fluids.
