Spiky development at the interface in Rayleigh-Taylor instability: Layzer approximation with second harmonic
Layzer second harmonic
2011/8/30
Layzer’s approximation method for investigation of two fluid interface structures associated with Rayleigh Taylor instability for arbitrary Atwood number is extended with the inclusion of second harmo...
Critical Magnetic Number in the MHD Rayleigh-Taylor instability
Rayleigh-Taylor instability MHD free boundary problem critical number
2010/12/14
We reformulate in Lagrangian coordinates the two-phase free boundary problem for the equations of Magnetohydrodynamics in a infinite slab, which is incompressible, vis-cous and of zero resistivity, as...
Crossover between Rayleigh-Taylor Instability and turbulent cascading atomization mechanism in the bag-breakup regime
Rayleigh-Taylor Instability bag-breakup regime atomization mechanism
2010/4/2
The question whether liquid atomization (or pulverization) resorts to instability dynamics (through refinements of Rayleigh-Plateau, Rayleigh-Taylor or Kelvin-Helmholtz mechanism) or to turbulent casc...
Evolution of unsteady jets in the Rayleigh-Taylor instability
unsteady jets Rayleigh-Taylor instability

The paper concerns the temporal evolution of the Rayleigh-Taylor instability of two superimposed fluids in a vertical channel. At large times the instability results in the formation of a wide nearly-...
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...
Nonuniform Approach to Terminal Velocity for Single Mode Rayleigh-Taylor Instability
Rayleigh-Taylor instability terminal velocity
2007/12/10
The temporal development of a single mode Rayleigh-Taylor instability consists of three stages: the linear, free fall and terminal velocity regimens. The purpose of this paper is to report on new phen...
