A New Approach to the Rayleigh-Taylor Instability. [PDF]
Arch Ration Mech Anal, 2021 AbstractIn this article we consider the inhomogeneous incompressible Euler equations describing two fluids with different constant densities under the influence of gravity as a differential inclusion. By considering the relaxation of the constitutive laws we formulate a general criterion for the existence of infinitely many weak solutions which reflect

The Inhibition of the Rayleigh-Taylor Instability by Rotation. [PDF]
Sci Rep, 2015 AbstractIt is well-established that the Coriolis force that acts on fluid in a rotating system can act to stabilise otherwise unstable flows. Chandrasekhar considered theoretically the effect of the Coriolis force on the Rayleigh-Taylor instability, which occurs at the interface between a dense fluid lying on top of a lighter fluid under gravity ...

Granular Rayleigh-Taylor Instability [PDF]
AIP Conference Proceedings, 2009 A granular instability driven by gravity is studied experimentally and numerically. The instability arises as grains fall in a closed Hele-Shaw cell where a layer of dense granular material is positioned above a layer of air. The initially flat front defined by the grains subsequently develops into a pattern of falling granu-lar fingers separated by ...

Rayleigh-Taylor instability in soft elastic layers. [PDF]
Philos Trans A Math Phys Eng Sci, 2017 This work investigates the morphological stability of a soft body composed of two heavy elastic layers attached to a rigid surface and subjected only to the bulk gravity force. Using theoretical and computational tools, we characterize the selection of different patterns as well as their nonlinear evolution, unveiling the interplay between elastic and ...

Centrifugally forced Rayleigh–Taylor instability [PDF]
Journal of Fluid Mechanics, 2018 We consider the effect of high rotation rates on two liquid layers that initially form concentric cylinders, centred on the axis of rotation. The configuration may be thought of as a fluid–fluid centrifuge. There are two types of perturbation to the interface that may be considered, an azimuthal perturbation around the circumference of the interface ...

Wave instability on the interface coating/substrate material under heterogeneous plasma flows
Journal of Materials Research and Technology, 2020 The paper reports on an undulating topography initiating on the interface “coating/base material” under heterogeneous plasma flows to be generated by an explosion of yttrium powder on the aluminum-silicon base. We assumed that an undulating topography on
