Understanding how turbulence leads to the enhanced irreversible transport of heat and
other scalars such as salt and pollutants in density-stratified fluids is a fundamental and …

We give a brief review of several prominent fluid instabilities representing transitions driven
by gravity, surface tension, thermal energy, and applied motion/acceleration. Strategies for …

Instabilities are present in all natural fluids from rivers to atmospheres. This book considers
the physical processes that generate instability. Part I describes the normal mode …

We consider numerically the transition to turbulence and associated mixing in stratified
shear flows with initial velocity distribution. Despite their vastly different mechanics (ie …

Motivated by the importance of diapycnal mixing parameterizations in large-scale ocean
general circulation models, we provide a detailed analysis of high-Reynolds-number mixing …

Finite-amplitude manifestations of stratified shear flow instabilities and their spatio-temporal
coherent structures are believed to play an important role in turbulent geophysical flows …

The asymmetric Holmboe instabilities that form on an arrested salt wedge are investigated in
the laboratory. The flow is characterized by three regions. Near the tip of the salt wedge …

The velocity perturbations and Reynolds stresses associated with finite-amplitude Holmboe
instabilities are investigated using linear stability analysis, numerical simulations, and …

We consider the influence of transverse confinement on the instability properties of velocity
and density distributions reminiscent of those pertaining to exchange flows in stratified …

When the stability of a sharply stratified shear flow is studied, the density profile is usually
taken stepwise and a weak stratification between pycnoclines is neglected. As a …
