Kelvin-Helmholtz versus Hall magneto-shear instability in astrophysical flows
(American Physical Society, 2014-05)
We study the stability of shear flows in a fully ionized plasma. Kelvin-Helmholtz is a well-known macroscopic and ideal shear-driven instability. In sufficiently low-density plasmas, also the microscopic Hall magnetoshear ...
Surface waves on Saturn's dawn flank magnetopause driven by the Kelvin-Helmholtz instability
Crossings of Saturn's magnetopause made by the Cassini spacecraft on 12, 13 and 17 March 2006 are analysed. During this period Cassini's trajectory was approximately parallel to the magnetopause boundary given by a model ...
One-dimensional two-fluid model for wavy flow beyond the Kelvin-Helmholtz instability: Limit cycles and chaos
(Elsevier Science Sa, 2016-12)
A 1D TFM numerical simulation of near horizontal stratified two-phase flow is performed where the TFM, including surface tension and viscous stresses, is simplified to a two-equation model using the fixed-flux approximation. ...
The magnetosphere mixing layer: Observations, MHD stability, and large eddy simulations
(Institute of Physics Publishing, 2011-03)
The work is about the evolution of large vortices in the boundary layer of the terrestrial magnetopause studied by computational physics, in support of interpretive analysis of spacecraft data from an event observed on ...
Vortex formation in sheared flow driven fluctuations in nonuniform magnetized dusty gases
(American Physical SocCollege PkEUA, 1998)
Simulations of the Kelvin-Helmholtz instability driven by coronal mass ejections in the turbulent corona
(IOP Publishing, 2016-02)
Recent high-resolution Atmospheric Imaging Assembly/Solar Dynamics Observatory images show evidence of the development of the Kelvin–Helmholtz (KH) instability, as coronal mass ejections (CMEs) expand in the ambient corona. ...
On the multispacecraft determination of periodic surface wave phase speeds and wavelengths
(Blackwell Publishing Ltd, 2010-09)
Observations of surface waves on the magnetopause indicate a wide range of phase velocities and wavelengths. Their multispacecraft analysis allows a more precise determination of wave characteristics than ever before and ...
A criterion for the equivalence of the Birkhoff-Rott and Euler descriptions of vortex sheet evolution
(Amer Mathematical SocProvidenceEUA, 2007)
Three-dimensional, fully adaptive simulations of phase-field fluid models
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2010)
We present an efficient numerical methodology for the 31) computation of incompressible multi-phase flows described by conservative phase-field models We focus here on the case of density matched fluids with different ...
Magnetosheath for almost-aligned solar wind magnetic field and flow vectors: Wind observations across the dawnside magnetosheath at x = -12 Re
(Blackwell Publishing Ltd, 2010-08)
While there are many approximations describing the flow of the solar wind past the magnetosphere in the magnetosheath, the case of perfectly aligned (parallel or anti-parallel) interplanetary magnetic field (IMF) and solar ...
