Nonlinear saturation of Rayleigh-Taylor instability and generation of shear flow in equatorial spread-F plasma
Nonlinear saturation Rayleigh-Taylor instability shear flow equatorial spread-F plasma
2009/11/12
An analysis of low order mode coupling equations is used to describe the nonlinear behaviour of the Rayleigh-Taylor (RT) instability in the equatorial ionosphere. The nonlinear evolution of RT instabi...
On the predominance of oblique disturbances in the supersonic shear flow instability of the geomagnetic tail boundary
oblique disturbances supersonic shear flow instability geomagnetic tail boundary
2009/11/12
A study is made of the influence of the longitudinal magnetic field and density inhomogeneity on the supersonic shear flow instability at the magnetospheric tail boundary. It is shown that the most un...
On the origin of time-dependent behaviour in a barotropically unstable shear layer
time-dependent behaviour unstable shear layer

An experimental study on the instability of a detached Stewartson layer, using an annular, rotating tank with flat, rigid upper and lower boundaries, showed an instability to steady vortices at a crit...
