Nonlinear dynamo in a short Taylor-Couette setup

, 2012
It is numerically demonstrated by means of a magnetohydrodynamics code that a short Taylor-Couette setup with a body force can sustain dynamo action. The magnetic threshold is comparable to what is usually obtained in spherical geometries.

STUDY OF MHD FLOW OF BLOOD WITH HEAT TRANSFER IN AN ARTERIAL SEGMENT UNDER THE EFFECT OF PERIODIC BODY ACCELERATION

, 2017
The aim of this paper is to study numerically the blood flow in an arterial segment in the presence of an externally applied magnetic field and body acceleration by considering the fluid to be incompressible and Newtonian.

Heat and Hall Effect of an Oscillating Plate in a Porous Medium [PDF]

, 2013
An exact solution of the flow of heat and viscous fluid on a porous plate by using perturbation is obtained for the conjugate problem of an electrically conducting fluid in the presence of strong magnetic field by introducing the Hall currents.

The Beale-Kato-Majda criterion to the 3D Magneto-hydrodynamics equations

, 2007
We study the blow-up criterion of smooth solutions to the 3D MHD equations. By means of the Littlewood-Paley decomposition, we prove a Beale-Kato-Majda type blow-up criterion of smooth solutions via the vorticity of velocity only, i. e.

On the regularity criteria for the 3D magneto-micropolar fluids in terms of one directional derivative

, 2012
In this paper, we establish two new regularity criteria for the 3D magneto-micropolar fluids in terms of one directional derivative of the velocity or of the pressure and the magnetic field.MSC:35Q35, 76W05, 35B65.

Initial boundary value problem and exponential stability for the planar magnetohydrodynamics equations with temperature-dependent viscosity

Advances in Nonlinear Analysis
In this study, we consider the initial boundary value problem of the planar magnetohydrodynamics (MHD) system when the viscous coefficients and heat conductivity depend on the temperature, which are assumed to be proportional to θα{\theta }^{\alpha }, α ...

On a stationary solution for the magnetohydrodynamic equations in a bounded domain [PDF]

, 2010
A stationary problem of the magnetohydrodynamic (MHD) equations in three dimensional bounded domain is considered. The MHD system is known as a mathematical model for the motion of viscous, incompressible and electrically conducting fluid and as a ...

Low Mach number and non-resistive limit of magnetohydrodynamic equations with large temperature variations in general bounded domains

Advances in Nonlinear Analysis
This article verifies the low Mach number and non-resistive limit of local strong solutions to non-isentropic compressible magnetohydrodynamic (MHD) equations in general three-dimensional bounded domains when the temperature variation is large but finite.

Positivity-Preserving Finite Difference WENO Schemes with Constrained Transport for Ideal Magnetohydrodynamic Equations [PDF]

, 2015
In this paper, we utilize the maximum-principle-preserving flux limiting technique, originally designed for high order weighted essentially non-oscillatory (WENO) methods for scalar hyperbolic conservation laws, to develop a class of high order ...
