Rayleigh–Taylor instability in a viscoelastic binary fluid [PDF]
Journal of Fluid Mechanics, 2010 The effects of polymer additives on Rayleigh–Taylor (RT) instability of immiscible fluids is investigated using the Oldroyd-B viscoelastic model. Analytic results obtained exploiting the phase-field approach show that in polymer solution the growth rate of the instability speeds up with elasticity (but remains slower than in the pure solvent case ...

Effects of the postsunset vertical plasma drift on the generation of equatorial spread F
Progress in Earth and Planetary Science, 2018 Equatorial spread F (ESF) irregularities are caused by plasma instability processes in the equatorial ionosphere and especially related to plasma bubble phenomena in the topside F region.

Experimental Factors and Techniques for Pool Boiling Heat Transfer Enhancement: A Critical Review
Heat Transfer, Volume 55, Issue 4, Page 2201-2232, June 2026.ABSTRACT This review presents a comprehensive assessment of active strategies for enhancing pool boiling heat transfer, with a focus on techniques that do not rely solely on the boiling surface modification. It examines a broad range of methodologies including fluid additives, external fields, mechanical interventions, and thermal‐geometric tuning that

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.Abstract Rifting is a tectonic process that leads to extensive magmatic activity, continental breakup, and the formation of new oceanic crust. The interplay between rifting and dynamic mantle flow driven by thermal heterogeneity in the mantle along the rift‐axis can influence magmatism and deformation beyond the rift zone.

Journal of Applied Fluid Mechanics, 2010 In this paper the effects of couple stress fluid on the control of Rayleigh-Taylor instability at the interface between a dense fluid accelerated by a lighter fluid is studied. A simple theory, based on fully developed approximations, is used to derive

Modeling hydrodynamic instabilities of double ablation fronts in inertial confinement fusion
EPJ Web of Conferences, 2013 A linear Rayleigh-Taylor instability theory of double ablation (DA) fronts is developed for direct-drive inertial confinement fusion. Two approaches are discussed: an analytical discontinuity model for the radiation dominated regime of very steep DA ...

Lunar Crustal Formation by Melt Migration and Differentiation Within a Stagnant Lid
Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.Abstract The lunar anorthosite highlands represent the Moon's primary crust, which formed during the solidification of a magma ocean following the Moon‐forming giant impact. However, the canonical model of anorthite flotation in the crystallizing magma ocean often struggles to reproduce the long > ${ >} $200 Myr solidification timescale required by the

Finite boundary effects on the spherical Rayleigh–Taylor instability between viscous fluids
AIP Advances, 2022 For the Rayleigh–Taylor unstable arrangement of a viscous fluid sphere embedded in a finite viscous fluid spherical shell with a rigid boundary and a radially directed acceleration, a dispersion relation is developed from a linear stability analysis ...
