Hall MHD and electron inertia effects in current sheet formation at a magnetic neutral line

, 2015
An exact self-similar solution is used to investigate current sheet formation at a magnetic neutral line in incompressible Hall magnetohydrodynamics. The collapse to a current sheet is modelled as a finite-time singularity in the solution for electric ...

On the asymptotic linking number [PDF]

, 2000
We prove a theorem formulated by V. I. Arnold concerning a relation between the asymptotic linking number and the Hopf invariant of divergence-free vector fields. Using a modified definition for the system of short paths, we prove their existence in the general case.

Generalized solutions of the fractional Burger’s equation

Results in Physics, 2019
We investigate the solutions for the fractional Burger’s equation based on the Jumarie fractional derivative using Bernoulli polynomials. We find general solutions for such problems. Comparison with other methods is presented.

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.

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 ...

The solution of Cahn-Allen equation based on Bernoulli sub-equation method

Results in Physics, 2019
In this article, we present an analytical method for finding the solutions of the Cahn-Allen equation (CAE) based on the Bernoulli sub-equation method (BSEM). We find an infinite number of solutions which are divided into eight families.

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.

Roe-type schemes for shallow water magnetohydrodynamics with hyperbolic divergence cleaning [PDF]

arXiv, 2014
We discuss Roe-type linearizations for non-conservative shallow water magnetohydrodynamics without and with hyperbolic divergence cleaning.

On the temporal decay for the Hall-magnetohydrodynamic equations [PDF]

arXiv, 2013
We establish temporal decay estimates for weak solutions to the Hall-magnetohydrodynamic equations. With these estimates in hand we obtain algebraic time decay for higher order Sobolev norms of small initial data solutions.
