Trans-Magnetosonic Accretion in a Black Hole Magnetosphere
, 2002 We present the critical conditions for hot trans-fast magnetohydrodynamical (MHD) flows in a stationary and axisymmetric black-hole magnetosphere. To accrete onto the black hole, the MHD flow injected from a plasma source with low velocity must pass ...

System Design Considerations for Magneto‐Electrocatalysis of the Oxygen Evolution Reaction
Small, EarlyView.Electrocatalytic water‐splitting can be controlled using a magnetic field. The commercial prospects are exciting, but the progress is stuck in the fundamental stage of research. Progress is stagnated by publications with conflicting results, incomplete analysis, and inconsistent experimental setups.

Non-linear damping of visco-resistive Alfven waves in solar spicules
, 2013 Interaction of Alfven waves with plasma inhomogeneities generates phase mixing which can lead to dissipate Alfven waves and to heat the solar plasma.

IET Power Electronics, EarlyView.Some of the topologies with a fewer number of power switches are reviewed and scrutinized. An extensive analysis of the topologies, control strategy and applications are presented here, suggesting suitable multilevel inverter solutions to the known industrial application or new research.

Minimum energy states of the plasma pinch in standard and Hall magnetohydrodynamics
, 2000 Axisymmetric relaxed states of a cylindrical plasma column are found analytically in both standard and Hall magnetohydrodynamics (MHD) by complete minimization of energy with constraints imposed by invariants inherent in corresponding models. It is shown

Existence of solutions for the MHD-Leray-alpha equations and their relations to the MHD equations
Journal of Mathematical Analysis and Applications, 2007 AbstractIn this paper we derive some new equations and we call them MHD-Leray-alpha equations which are similar to the MHD equations. We put forward the concept of weak and strong solutions for the new equations. Whether the 3-dimensional MHD equations have a unique weak solution is unknown, however, there is a unique weak solution for the 3 ...

The mathematical theory of reduced MHD models for fusion plasmas [PDF]
arXiv, 2015 The derivation of reduced MHD models for fusion plasma is here formulated as a special instance of the general theory of singular limit of hyperbolic system of PDEs with large operator. This formulation allows to use the general results of this theory and to prove rigorously that reduced MHD models are valid approximations of the full MHD equations. In
