First Principles Description of Plasma Expansion Using the Expanding Box Model

Universe, 2023
Multi-scale modeling of expanding plasmas is crucial for understanding the dynamics and evolution of various astrophysical plasma systems such as the solar and stellar winds. In this context, the Expanding Box Model (EBM) provides a valuable framework to

One-form superfluids & magnetohydrodynamics

Journal of High Energy Physics, 2020
We use the framework of generalised global symmetries to study various hydrodynamic regimes of hot electromagnetism. We formulate the hydrodynamic theories with an unbroken or a spontaneously broken U(1) one-form symmetry. The latter of these describes a

Magnetohydrodynamics of blood flow [PDF]

Magnetic Resonance in Medicine, 1990
AbstractThe changes in hydrostatic pressure and electrical potentials across vessels in the human vasculature in the presence of a large static magnetic field are estimated to determine the feasibility of in vivo NMR spectroscopy at fields as high as 10 T.

Relativistic magnetohydrodynamics

Journal of High Energy Physics, 2017
We present the equations of relativistic hydrodynamics coupled to dynamical electromagnetic fields, including the effects of polarization, electric fields, and the derivative expansion.

Monolithic Multigrid for Magnetohydrodynamics

CoRR, 2020
The magnetohydrodynamics (MHD) equations model a wide range of plasma physics applications and are characterized by a nonlinear system of partial differential equations that strongly couples a charged fluid with the evolution of electromagnetic fields.

Experimental, numerical and analytical evaluation of -thrust for fast-liquid-metal-flow divertor systems of nuclear fusion devices

Nuclear Fusion, 2023
Divertor systems of fusion devices are exposed to intense heat loads from plasmas, which degrade solid plasma-facing components. Fast liquid metal (LM) flow divertors may be more advantageous for this purpose but have risk of piling due to intense ...

Probing non-linear MHD stability of the EDA H-mode in ASDEX Upgrade

Nuclear Fusion, 2023
Regimes of operation in tokamaks that are devoid of large edge localised modes have to be better understood to extrapolate their applicability to reactor-relevant devices.
