Analytical Study of Certain Magnetohydrodynamic-alpha Models

open access: yes, 2006
In this paper we present an analytical study of a subgrid scale turbulence model of the three-dimensional magnetohydrodynamic (MHD) equations, inspired by the Navier-Stokes-alpha (also known as the viscous Camassa-Holm equations or the Lagrangian ...

Application of the effective resistivity in MHD and Hall MHD simulations for collisionless magnetic reconnection [PDF]

open access: yesarXiv, 2022
The off-diagonal electron pressure terms are well-known for the frozen-in condition breakdown in collisionless magnetic reconnection, but are naturally kinetic and hard to employ in magnetohydrodynamics (MHD) simulations. Considering the inadequacy of MHD and Hall MHD in neglecting the important electron dynamics like inertia item and nongyrotropic ...

The Simplest Resonant Spin--Flavour Solution to the Solar Neutrino Problem [PDF]

open access: yes, 2000
We re-analyse the resonant spin-flavour (RSF) solutions to the solar neutrino problem in the framework of analytic solutions to the solar magneto-hydrodynamics (MHD) equations.

Multi‐Scaled Cellulosic Nanonetworks from Tunicates

open access: yesAdvanced Functional Materials, EarlyView.
Microbial and plant nanonetworks of cellulose have enabled a wide range of high‐performance yet sustainable materials. Herein, a third class of cellulosic nanonetworks is showcased by exploiting the only animal tissue‐producing cellulose nanofibers, i.e., ascidians. An ultrastructure including spherical cells and a microvasculature with diameters of 50–

Analysis of Magnetohydrodynamic (MHD) Nanofluid Flow with Heat and Mass Transfer Over a Porous Stretching Sheet

open access: yesInternational Journal of Applied Mechanics and Engineering, 2020
This work investigates a three-dimensional Magnetohydrodynamic (MHD) nanofluid flow with heat and mass transfer over a porous stretching sheet. Firstly, partial differential equations are transformed into coupled non-linear ordinary differential ...

Liouville--type Theorems for Steady MHD and Hall--MHD Equations in $\R^2 \times \T$ [PDF]

open access: yesarXiv, 2022
In this paper, we study the Liouville--type theorems for three--dimensional stationary incompressible MHD and Hall--MHD systems in a slab with periodic boundary condition. We show that, under the assumptions that $(u^\theta,b^\theta)$ or $(u^r,b^r)$ is axisymmetric, or $(ru^r,rb^r)$ is bounded, any smooth bounded solution to the MHD or Hall--MHD system

Dynamic Alignment and Exact Scaling Laws in MHD Turbulence

open access: yes, 2009
Magnetohydrodynamic (MHD) turbulence is pervasive in astrophysical systems. Recent high-resolution numerical simulations suggest that the energy spectrum of strong incompressible MHD turbulence is $E(k_{\perp})\propto k_{\perp}^{-3/2}$. So far, there has

General-Relativistic MHD for the Numerical Construction of Dynamical Spacetimes [PDF]

open access: yes, 2002
We assemble the equations of general relativistic magnetohydrodynamics (MHD) in 3+1 form. These consist of the complete coupled set of Maxwell equations for the electromagnetic field, Einstein's equations for the gravitational field, and the equations of
