Sunspot Modeling: From Simplified Models to Radiative MHD Simulations

Living Reviews in Solar Physics, 2011
We review our current understanding of sunspots from the scales of their fine structure to their large scale (global) structure including the processes of their formation and decay. Recently, sunspot models have undergone a dramatic change.

Non-Stationary Flow of a Viscous Incompressible Electrically Conductive Liquid on a Rotating Plate in the Presence of Media Injection (Suction), Considering Induction and Diffusion Effects

Physics
The branch of physics known as magnetohydrodynamics (MHD) emerged in the middle of the 20th century. MHD models, being substantially nonlinear, are quite challenging for theoretical study and allow nontrivial consideration only in particular limited ...

A Galerkin Finite Element Method for the Reconstruction of a Time-Dependent Convection Coefficient and Source in a 1D Model of Magnetohydrodynamics

Applied Sciences
The mathematical analysis of viscous magnetohydrodynamics (MHD) models is of great interest in recent years. In this paper, a finite element Galerkin method is employed for the estimation of an unknown time-dependent convection coefficient and source in ...

Magnetohydrodynamic Analysis and Fast Calculation for Fractional Maxwell Fluid with Adjusted Dynamic Viscosity

Magnetochemistry
From the perspective of magnetohydrodynamics (MHD), the heat transfer properties of Maxwell fluids under MHD conditions with modified dynamic viscosity present complex challenges in numerical simulations.

Nonexistence of self-similar singularities in ideal viscoelastic flows

Electronic Journal of Differential Equations, 2012
We prove the nonexistence of finite time self-similar singularities in an ideal viscoelastic flow in R^3. We exclude the occurrence of Leray-type self-similar singularities under suitable integrability conditions on velocity and deformation tensor ...

Observations and Simulations of a Double‐Core Hot Flow Anomaly

Geophysical Research Letters
Hot Flow anomalies (HFAs), one of the most well‐analyzed transient phenomena in the Earth's foreshock, are known as kinetic structures driven by tangential discontinuities (TDs).

Global Existence of Smooth Solutions to an Initial-Boundary Value Problem of One-Dimensional MHD–Vlasov Equations

Journal of Function Spaces
In this paper, the existence and uniqueness of the global smooth solution to an initial-boundary value problem of one-dimensional magnetohydrodynamics (MHD)–Vlasov equations are proved for large initial data.
