Rayleigh–Taylor-instability (RTI) induced flow and mixing are of great importance in both
nature and engineering scenarios. To capture the underpinning physics, tracers are …

Abstract The two-dimensional Rayleigh–Taylor Instability (RTI) under multi-mode
perturbation in compressible flow is probed via the Discrete Boltzmann Modeling (DBM) with …

Turbulent mixing induced by Rayleigh-Taylor (RT) instability occurs ubiquitously in many
natural phenomena and engineering applications. As the simplest and primary descriptor of …

Rayleigh-Taylor instability occurs when two uids are separated by an interface, and an
accelerating force, such as gravity, is directed from the heavy uid to the light uid. This type of …

Three-dimensional direct numerical simulations (DNS) of Rayleigh-Taylor instability (RTI) at
the interface of two masses of air with a sharp temperature gradient of 149 K are performed …

The focus of experiments and the sophistication of diagnostics employed in Rayleigh-Taylor
instability (RTI) induced mixing studies have evolved considerably over the past seven …

This paper describes an experimental investigation of mixing due to Rayleigh–Taylor
instability between two miscible fluids. Attention is focused on the gravitationally driven …

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 …

Direct numerical simulations (DNS) are presented of three-dimensional, Rayleigh–Taylor
instability (RTI) between two incompressible, miscible fluids, with a 3: 1 density ratio …

High-Reynolds-number turbulence generated by Rayleigh–Taylor instability is known to be
much more efficient at mixing density-stratified fluids than mixing driven by most other …
