Stratified Taylor-Couette flow: nonlinear dynamics [PDF]
, 2022 A series of experiments on stratified Taylor–Couette flow in short aspect ratio wide-gap annuli found an intriguing and not-well-understood dynamics: nonlinear coherent structures appearing and disappearing periodically, along with density layering ...

On effect of surface tension in the Rayleigh–Taylor problem of stratified viscoelastic fluids
Boundary Value Problems, 2019 In this article, we investigate the effect of surface tension in the Rayleigh–Taylor (RT) problem of stratified incompressible viscoelastic fluids. We prove that there exists an unstable solution to the linearized stratified RT problem with a largest ...

Shape and size of large-scale vortices: A generic fluid pattern in geophysical fluid dynamics
Physical Review Research, 2020 Planetary rotation organizes fluid motions into coherent, long-lived swirls, known as large-scale vortices (LSVs), which play an important role in the dynamics and long-term evolution of geophysical and astrophysical fluids.

Numerical modeling of inclined plane jets in a linearly stratified environment
Alexandria Engineering Journal, 2020 Wastewater discharges are widespread in industrial and natural environments, and since these discharges may cause serious impacts on the environment and ecological systems, it is important to investigate their mixing processes.

Rayleigh-Taylor Instability for Adiabatically Stratified Fluids [PDF]
, 1989 A linear analysis of the effects of compressibility on the stability of two superposed isentropic fluids is presented. The results of the analysis, which differ from those available in the literature for other unperturbed stratifications, are illustrated

Bubble plumes in a stratified environment: Source parameters, scaling, intrusion height, and neutral height [PDF]
, 2017 A cross-sectionally averaged model is used to study several aspects of the physics of a bubble plume rising in a stratified quiescent liquid. Scaling analyses for the peel height, at which the plume momentum vanishes, and the neutral height, at which its
