Lie Group Solutions of Magnetohydrodynamics Equations and Their Well-Posedness

Abstract and Applied Analysis, 2016
Based on classical Lie Group method, we construct a class of explicit solutions of two-dimensional ideal incompressible magnetohydrodynamics (MHD) equation by its infinitesimal generator. Via these explicit solutions we study the uniqueness and stability

Parameter Determination Method of Cassie-Mayr Hybrid Arc Model Based on Magnetohydrodynamics Plasma Theory

Frontiers in Energy Research, 2022
This paper proposes an improved alternating current (AC) arc model based on the Cassie-Mayr hybrid model and magnetohydrodynamics (MHD) theory. The undetermined parameters of the traditional Cassie-Mayr arc model are mainly obtained by subjective methods

Linear stability of certain translationally symmetric MHD equilibria with incompressible flow

Results in Physics, 2017
In this paper, the linear stability analysis for ideal incompressible magnetohydrodynamic (MHD) flows is investigated. MHD flows in cylindrical domains with arbitrary cross-section as well as circular cross-section are considered.

Regularity results for a model in magnetohydrodynamics with imposed pressure

Comptes Rendus. Mathématique, 2021
The magnetohydrodynamics (MHD) problem is most often studied in a framework where Dirichlet type boundary conditions on the velocity field is imposed. In this Note, we study the (MHD) system with pressure boundary condition, together with zero tangential

Constrained hyperbolic divergence cleaning in smoothed particle magnetohydrodynamics with variable cleaning speeds [PDF]

, 2016
We present an updated constrained hyperbolic/parabolic divergence cleaning algorithm for smoothed particle magnetohydrodynamics (SPMHD) that remains conservative with wave cleaning speeds which vary in space and time. This is accomplished by evolving the
