Comment on “Magnetohydrodynamic simulations of direct current helicity injection for current drive in tokamaks’’ [Phys. Plasmas 3, 1038 (1996)] [PDF]
Physics of Plasmas, 1997 We disagree with the conclusions of the previous paper because reaching negative conclusions about helicity injection current drive for tokamaks based on magnetohydrodynamic simulation is unjustified. (AIP)

Response to “Comment on ‘Magnetohydrodynamic simulations of direct current helicity injection for current drive in tokamaks’ ’’ [Phys. Plasmas 3, 1038 (1996)] [PDF]
Physics of Plasmas, 1997 We agree that additional effects (toroidicity, Hall and rotamak effects, and Lundquist number scaling) will alter the physics and magnetohydrodynamic simulation of HIT experiments. Future research will clarify the importance of these effects. (AIP)

This work introduces a hybrid theoretical concept for plasma-based gas acceleration, combining controlled pre-ionization of a working gas with magnetohydrodynamic (MHD) forcing inside a duct geometry. The pre-ionization stage increases the electrical conductivity σ, enabling stronger current densities and Lorentz forces (F = J × B) for a given electric

Chromospheric Jets and Their Properties [PDF]
Iranian Journal of Astronomy and Astrophysics, 2022 In this study we review solar chromospheric jets and characteristics of them. The chromosphere and transition region are the interface between the solar photosphere and the corona, which plays a key role in the formation and acceleration of the solar ...

Plasma Flows in Solar Filaments as Electromagnetically Driven Vortical Flows
Physics, 2021 Electromagnetic expulsion acts on a body suspended in a conducting fluid or plasma, which is subject to the influence of electric and magnetic fields. Physically, the effect is a magnetohydrodynamic analogue of the buoyancy (Archimedean) force, which is ...

Anomalous Scaling in the Kinematic Magnetohydrodynamic Turbulence [PDF]
EPJ Web of Conferences, 2020 The problem of the anomalous scaling in the kinematic magnetohydrodynamic turbulence is investigated using the field theoretic renormalization group method and the operator product expansion technique.
