Photospheric magnetic vortex structures [PDF]

, 2011
Using direct numerical magneto-hydrodynamic (MHD) simulations, we demonstrate the evidence of two physically different types of vortex motions in the solar photosphere.

On the Richtmyer-Meshkov Instability in Magnetohydrodynamics [PDF]

, 2005
The Richtmyer-Meshkov instability is important in a wide variety of applications including inertial confinement fusion and astrophysical phenomena. In some of these applications, the fluids involved may be plasmas and hence be affected by magnetic fields.

A sufficient condition for a finite-time $L_2 $ singularity of the 3d Euler Equations [PDF]

, 2005
A sufficient condition is derived for a finite-time $L_2 $ singularity of the 3d incompressible Euler equations, making appropriate assumptions on eigenvalues of the Hessian of pressure.

Spatial distribution of rolled up Kelvin-Helmholtz vortices at Earth's dayside and flank magnetopause [PDF]

, 2012
The Kelvin-Helmholtz Instability (KHI) can drive waves at the magnetopause. These waves can grow to form rolled-up vortices and facilitate transfer of plasma into the magnetosphere.

The Creation of a Vortex in Sea water through the MHD [PDF]

, 2018
The Magneto hydrodynamics equations, MHD, are discussed for weakly conductive fluids of electricity, and then an analytical solution is presented. An MHD vortex is generated using seawater in a cylindrical vessel, where external electromagnetic fields ...

Vortex flow generator utilizing synthetic jets by diaphragm vibration [PDF]

, 2018
This paper develops a millimeter scale fully packaged device in which a vortex flow of high velocity is generated inside a chamber. Under the actuation by a lead zirconate titanate (PZT) diaphragm, a flow circulates with increasing velocity after each ...

Kinetic helicity and MHD turbulence

, 2000
The issue of dynamical anisotropy in helical three-dimensional magnetohydrodynamic turbulence with a mean magnetic field B₀ is investigated. Using high-resolution direct numerical simulations, we follow the evolution of various isotropic initial states ...

The combined Lagrangian advection method [PDF]

, 2010
We present and test a new hybrid numerical method for simulating layerwise-two-dimensional geophysical flows. The method radically extends the original Contour-Advective Semi-Lagrangian (CASL) algorithm by combining three computational elements for the ...

Critical balance in magnetohydrodynamic, rotating and stratified turbulence : towards a universal scaling conjecture [PDF]

, 2009
It is proposed that critical balance - a scale-by-scale balance between the linear propagation and nonlinear interaction time scales - can be used as a universal scaling conjecture for determining the spectra of strong turbulence in anisotropic wave ...
