Hydrodynamics of higher-rank gauge theories

open access: yesSciPost Physics, 2023
We extend recent work on hydrodynamics with global multipolar symmetries — known as "fracton hydrodynamics" — to systems in which the multipolar symmetries are gauged.

The inviscid limit for the incompressible stationary magnetohydrodynamics equations in three dimensions

open access: yesBulletin of Mathematical Sciences, 2022
This paper is concerned with the zero-viscosity limit of the three-dimensional (3D) incompressible stationary magnetohydrodynamics (MHD) equations in the 3D unbounded domain [Formula: see text]. The main result of this paper establishes that the solution

A Blow-Up Criterion for 3D Nonhomogeneous Incompressible Magnetohydrodynamic Equations with Vacuum

open access: yesJournal of Function Spaces, 2022
For the strong solutions of the nonhomogeneous incompressible magnetohydrodynamics (MHD) system with vacuum, we establish a blow-up criterion for this system in terms of uC0,T;L3ℝ3. Moreover, the result generalizes previous ones in Giga (1986) and He and

Prediction of Entrance Length for Magnetohydrodynamics Channels Flow using Numerical simulation and Artificial Neural Network [PDF]

open access: yesJournal of Applied and Computational Mechanics, 2020
This paper focuses on using the numerical finite volume method (FVM) and artificial neural network (ANN) in order to propose a correlation for computing the entrance length of laminar magnetohydrodynamics (MHD) channels flow.

A new method to suppress the MHD instability of cylindrical liquid metal batteries [PDF]

open access: yesE3S Web of Conferences, 2023
The magnetohydrodynamics (MHD) instabilities of liquid metal batteries (LMBs) severely limit the wide application and commercialization of LMB. A new technology is proposed, which is called the gridstructure (GS), so as to achieve the suppression effect ...

Magnetohydrodynamic with Adaptively Embedded Particle-in-Cell model: MHD-AEPIC [PDF]

open access: yesJournal of Computational Physics, 2021
Space plasma simulations have seen an increase in the use of magnetohydrodynamic (MHD) with embedded Particle-in-Cell (PIC) models. This combined MHD-EPIC algorithm simulates some regions of interest using the kinetic PIC method while employing the MHD description in the rest of the domain.

Magnetohydrodynamic (MHD) Waves in Plasmas

open access: yesمجلة كلية التربية العلمية, 2022
The model for a magnetoplasma is given by the MHD equations, so the first aim is to give a full list of MHD equations, with the criteria of their applicability for wave propagation. The validity conditions under which the MHD equations are used require the wave frequency to be,  and the seven eigenvectors are obtained.
