Mhd turbulence: a biased review
WebbIn this talk, I will attempt a different (and perhaps more difficult) task, viz., to explain how several distinct (and distinctive) intellectual threads of MHD turbulence theory pursued by different groups of researchers over the last few decades are coming together in the emerging overall narrative: the critical-balance phenomenology (Goldreich … Webb1 okt. 2024 · This completes the picture of the MHD cascade at large scales.

Webb17 okt. 2024 · In this Letter, we study the role of the plasmoid instability in two-dimensional magnetohydrodynamic (MHD) turbulence by means of high-resolution direct numerical simulations. At a sufficiently large magnetic Reynolds number ( R m = 10 6 ), the combined effects of dynamic alignment and turbulent intermittency lead to a copious formation of … Webbfor a long time. They are fully helical, but they eventually become unstable and turbulence finally develops and decays at the same rate as for random fields, if later. In MHD, Alfvén waves, with u=±φ b, are well-known as well. Note that these Beltrami (force-free) solutions have been generalized to Hall-MHD as ∇×j−φj+μb=0[28].
WebbThe near-Earth space is a unique laboratory to explore turbulence and energy dissipation processes in magnetized plasmas thanks to the availability of high-quality data from various orbiting spacecraft, such as Wind, Stereo, Cluster, Themis, and the more recent one, the NASA Magnetospheric Multiscale (MMS) mission. In comparison with the solar …
