A rarefied gas between two coaxial circular cylinders of infinite length, rotating with different
angular velocities and kept at a common temperature, is considered. The stability of the …

Abstract Effects of two compressibility parameters, ie the ratio of specific heats and the
equilibrium pressure at the interface, on the Rayleigh–Taylor instability (RTI) growth rates …

The three-dimensional Rayleigh-Taylor instability is studied in a low Atwood number (A≈
0.15) miscible fluid system. The two fluids are contained within a Plexiglas tank that is …

A tentative review is presented of various approaches for numerical simulations of two-fluid
gaseous mixtures at high density ratios, as they have been applied to the Rayleigh–Taylor …

Hydrodynamic instabilities such as Rayleigh–Taylor (RT) and Richtmyer–Meshkov (RM)
instabilities usually appear in conjunction with the Kelvin–Helmholtz (KH) instability and are …

Rayleigh–Taylor instability (RTI) occurs when the interface between two fluids of different
densities is removed, with the heavier (cold) fluid resting on top of the lighter (hot) fluid in the …

ABSTRACT A numerical investigation of Rayleigh–Taylor instability (RTI) with different
unstable thermal stratifications, and coupled Kelvin–Helmholtz (KH) and RTI (referred to as …

Abstract The Rayleigh–Taylor instability is a fundamental instability of an interface between
two fluids of different densities, which occurs when the light fluid is pushing the heavy fluid …

The evolution of the multimode Rayleigh-Taylor instability of nearly incompressible fluids,
with density ratio r= 2, is investigated by means of two-dimensional hydrodynamic …

This study focuses on understanding the time-dependent anisotropy, mixing, scaling of flows
induced by Rayleigh-Taylor instability, and complementing the late-time snapshots reported …
