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 ...
Persistence of a Kelvin-Helmholtz instability complex in the upper troposphere
(American Geophysical Union, 2005-07-27)
During the period of 7–14 September 1998 a multiple instrument campaign was conducted at the Jicamarca Radio Observatory (JRO) near Lima, Peru, using a 50-MHz VHF radar and radiosondes. In this paper we discuss the radar ...
Aspects of magnetopause/magnetosphere response to interplanetary discontinuities, and features of magnetopause Kelvin-Helmholtz waves
(Elsevier, 2011-01)
We describe (i) perturbations of the magnetopause/magnetosphere elicited by an interplanetary discontinuity and (ii) the production of Kelvin-Helmholtz waves on the magnetopause. These are two large topics, so for reasons ...
Surface waves on Saturn's dawn flank magnetopause driven by the Kelvin-Helmholtz instability
(Elsevier, 2009-12)
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 ...
Investigação da estabilidade de escoamentos de jatos viscoelásticos
(Universidade Estadual Paulista (Unesp), 2020-09-28)
O estudo do escoamento de jato é relevante devido à sua importância em aplicações industriais, tais como, sistemas de propulsão, troca de calor e massa e estabilização de tiras, placas e blocos durante o tratamento térmico ...
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 ...
