The spatial structure and energy budget for Rayleigh-Taylor instability are examined using
results from a 512× 512× 2040 point direct numerical simulation. The outer-scale Reynolds …

The turbulent Rayleigh–Taylor instability is investigated in the limit of strong mode-coupling
using a variety of high-resolution, multimode, three dimensional numerical simulations NS …

Turbulent mixing due to the Rayleigh-Taylor instability is experimentally found to vary
strongly with the temporal acceleration profile g (t). For constant g, the bubble amplitude hb …

The dynamics of an interfacial flow that is initially Rayleigh-Taylor unstable but becomes
statically stable for some intermediate period due to the reversal of the externally imposed …

A large-eddy simulation technique is described for computing Rayleigh–Taylor instability.
The method is based on high-wavenumber-preserving subgrid-scale models, combined with …

In the turbulent Rayleigh–Taylor instability, the light fluid penetrates the heavy fluid as

We describe numerical simulations of the miscible Rayleigh-Taylor (RT) instability driven by
a complex acceleration history, g (t), with initially destabilizing acceleration, g> 0, an …

The effect of shear on the development of Rayleigh-Taylor instability (RTI) is studied at an
Atwood number of 0.035 using the gas tunnel at Texas A&M University. Two types of …
