A comparative study of data-driven MHD simulations of solar coronal evolution with photospheric flows derived from two different approaches

Frontiers in Astronomy and Space Sciences, 2023
Data-driven simulation proves to be a powerful tool in revealing the dynamic process of the solar corona, but it remains challenging to implement the driving boundary conditions in a self-consistent way and match the observables at the photosphere. Here,

An analytical, phenomenological and numerical study of geophysical and magnetohydrodynamic turbulence in two dimensions [PDF]

, 2013
In this thesis I study a variety of two-dimensional turbulent systems using a mixed analytical, phenomenological and numerical approach. The systems under consideration are governed by the two-dimensional Navier-Stokes (2DNS), surface quasigeostrophic

Impact of Hall effect on energy decay in magnetohydrodynamic turbulence [PDF]

, 2003
We examine numerically the influence of Hall effect corrections to Ohm's law upon the decay of homogeneous compressible magnetohydrodynamic turbulence and conclude that there are no significant differences in global decay rate associated with the Hall ...

The Effect of Magneto-hydrodynamics on Curved Circular Plate and Porous-rough Flat Plate with Non-Newtonian Fluid [PDF]

Journal of Applied and Computational Mechanics
This study explores the effect of theoretical MHD on curved circular and flat plates using non-Newtonian lubricant. Lower flat plate is porous and rough. The Stokes theory has been used to incorporate the couple stress effects.

Radiative MHD Nanofluid Flow over a Moving Thin Needle with Entropy Generation in a Porous Medium with Dust Particles and Hall Current

Entropy, 2020
This paper investigated the behavior of the two-dimensional magnetohydrodynamics (MHD) nanofluid flow of water-based suspended carbon nanotubes (CNTs) with entropy generation and nonlinear thermal radiation in a Darcy−Forchheimer porous medium over

Trefftz type method for 2D problems of electromagnetic scattering from inhomogeneous bodies

Computer Assisted Methods in Engineering and Science, 2023
A new numerical method for scattering from inhomogeneous bodies is presented. The cases of E and H-polarizated incident wave scattered by an infinite 2D cylinder are considered. The scattered field is looked for in two different domains.

A 2D Multiphase Model of Drop Behavior during Electroslag Remelting

Metals, 2020
Electroslag remelting is a process extensively used to produce metallic ingots with high quality standards. During the remelting operation, liquid metal droplets fall from the electrode through the liquid slag before entering the liquid pool of the ...
