Wave propagation, phase mixing and dissipation in Hall MHD [PDF]

open access: yes, 2012
In this thesis the effect of the Hall term in the generalised Ohm’s law on Alfvén (shear) and fast wave propagation and dissipation in the ion cyclotron frequency range is investigated.

Inspection of Couette and pressure-driven Poiseuille entropy-optimized dissipated flow in a suction/injection horizontal channel: Analytical solutions

open access: yesOpen Physics, 2023
The main aim of this study is to analyse the electrically conductive flow of compressible liquids by two infinitely permeable surfaces. The distance between the two surfaces is hh. Thermal relation consists of viscous dissipation.

Numerical Study of a Liquid Metal Oscillating inside a Pore in the Presence of Lorentz and Capillary Forces

open access: yesFluids, 2020
In order to ensure stable power exhaust and to protect the walls of fusion reactors, liquid metals that are fed to the wall surface through a capillary porous system (CPS) are considered as alternative plasma-facing components (PFCs).

Meromorphy and topology of localized solutions in the Thomas–MHD model [PDF]

open access: yes, 2001
The one-dimensional MHD system first introduced by J.H. Thomas [Phys. Fluids 11, 1245 (1968)] as a model of the dynamo effect is thoroughly studied in the limit of large magnetic Prandtl number.

Collisional and viscous damping of MHD waves in partially ionized plasmas of the solar atmosphere [PDF]

open access: yes, 2004
Magnetohydrodynamic (MHD) waves are widely considered as a possible source of heating for various parts of the outer solar atmosphere. Among the main energy dissipation mechanisms which convert the energy of damped MHD waves into thermal energy are ...

On the relationship between equilibrium bifurcations and ideal MHD instabilities for line-tied coronal loops [PDF]

open access: yes, 2010
For axisymmetric models for coronal loops the relationship between the bifurcation points of magnetohydrodynamic (MHD) equilibrium sequences and the points of linear ideal MHD instability is investigated, imposing line-tied boundary conditions.
