Global simulations of kinetic-magnetohydrodynamic processes with energetic electrons in tokamak plasmas

Nuclear Fusion, 2023
The energetic electrons (EEs) produced from auxiliary heatings have been found to destabilize various Alfven eigenmodes (AEs) in recent experiments. To investigate EE relevant kinetic-magnetohydrodynamic (MHD) processes, a global fluid-kinetic hybrid ...

The Inherently Three-Dimensional Nature of Magnetized Plasma Turbulence

, 2014
It is often asserted or implicitly assumed, without justification, that the results of two-dimensional investigations of plasma turbulence are applicable to the three-dimensional plasma environments of interest.

Sub‐Auroral Heating at Jupiter Following a Solar Wind Compression

Geophysical Research Letters, Volume 52, Issue 7, 16 April 2025.
Abstract Jupiter's polar aurorae deliver significant heating at the poles, thought to spread across the planet through atmospheric winds. Additionally, ground‐based Keck observations have revealed a large‐scale high‐temperature region, spatially distinct from the aurorae.

The Eddy Flux Transport of the Magnetohydrodynamic Quasi‐Geostrophic Disturbances

Geophysical Research Letters, Volume 52, Issue 7, 16 April 2025.
Abstract The classic Eliassen‐Palm (E‐P) flux in the geophysical fluid dynamics is a vector to qualify the eddy momentum and heat flux transport by Rossby waves in the latitude‐height plane. In this investigation, we derive two magnetic E‐P fluxes to quantify the eddy energy transport by magnetic Rossby waves by using magnetohydrodynamic quasi ...

Numerical Study of Radiative and Dissipative MHD Casson Nanofluid Over a Cone With High‐Order Chemical Reaction

Engineering Reports, Volume 7, Issue 4, April 2025.
This study investigated the dissipative effects on time‐dependent Casson nanofluid motion over a cone, considering variable heat source/absorption and higher‐order reacting species. Water ethylene glycol was employed as the Casson base fluid. The proposed model has broad applicability across various scientific, engineering, and technological domains ...

On Lyapunov boundary control of unstable magnetohydrodymanic plasmas [PDF]

arXiv, 2012
Starting from a simple marginally stable model considered for Lyapunov based boundary control of flexible mechanical systems, we add a term driving an instability and prove that for an appropriate control condition the system can become Lyapunov stable.

Solar wind driving of magnetospheric ULF waves: Field line resonances driven by dynamic pressure fluctuations [PDF]

, 2010
Several observational studies suggest that solar wind dynamic pressure fluctuations can drive magnetospheric ultra-low frequency (ULF) waves on the dayside. To investigate this causal relationship, we present results from Lyon-Fedder-Mobarry (LFM) global, three-dimensional magnetohydrodynamic (MHD) simulations of the solar wind-magnetosphere ...

Influence of Joule Heating and Nonlinear Thermal Radiation on the Electrical Conductivity of Second‐Grade Hybrid Nanofluid Flow Over a Stretching Cylinder

Engineering Reports, Volume 7, Issue 4, April 2025.
The present study investigates heat and mass transfer of electrically conducting second‐grade hybrid nanofluid flow over a stretching cylinder in the presence of nonuniform heat sources and nonlinear thermal radiation. The application of such hybrid nanofluid in second‐grade fluid flow can significantly enhance thermal conductivity and heat transfer ...
