Annual Review of Fluid Mechanics, 1979
In this article we review research activities concerning wakes generated by moving bodies in stratified fluids. A wake is defined to be the non propagating disturbance produced by a moving body, and thus research activities concerning internal waves generated by a moving body are not included.

Turbulent Mixing in Stratified Fluids
Annual Review of Fluid Mechanics, 1991ion layer in the oceanic benthic boundary layer against the stratification of the lutocline, and the growth of the planetary boundary layer (PBL) due to the turbulent mixing at the tropopause. Such mixing processes are of importance in studying and controlling various biological activities and the dispersion of pollutants in the environment.

Journal of Fluid Mechanics, 1968
The general nature of the flow at large distances from a two-dimensional body moving uniformly through an unbounded, linearly stratified, non-diffusive viscous fluid is considered. The governing equations are linearized using the Oseen and Boussinesq approximations, and the boundary conditions at the body are replaced by a linearized momentum-integral ...

Wake Collapse in a Stratified Fluid
Science, 1967A two-dimensional model is used to obtain quantitative data on characteristics of turbulently mixed wakes of bodies submerged in stratified fluids (more dense below than above). The time between turbulent mixing and maximum expansion of the wake before vertical collapse starts is 0.44 T , where T

Turbulent Trailing Vortices in Stratified Fluids
AIAA Journal, 1980The effects of stable atmospheric-density stratification, vortex core size, and turbulent scale on the descent of aircraft-trailing vortices are investigated using numerical solutions of a second-order closure turbulence model. A Boeing 747 vortex descent is simulated numerically and compared to reported measurements of descent distance, velocity, and ...

Squire’s theorem for two stratified fluids
The Physics of Fluids, 1986It is demonstrated that only two-dimensional perturbations need be considered in determining the marginal stability boundary in the parameter space for the incompressible, parallel flow of two stratified, homogeneous, immiscible fluids, with constant interfacial tension, bounded by two (possibly moving) parallel plates.

Vortices and Vortex Rings of Stratified Fluids
SIAM Journal on Applied Mathematics, 1975Exact solutions for finite-amplitude motion of an inviscid, incompressible and stratified fluid corresponding to rectilinear vortices or vortex rings are found. Some of the rectilinear vortex pairs, in circular-cylindrical form, can propagate with a constant horizontal velocity in a surrounding homogeneous fluid, and some of the spherical vortex rings ...

Decay of monopolar vortices in a stratified fluid
Fluid Dynamics Research, 1998Summary: The decay of monopolar vortices in a stratified fluid has been investigated experimentally, and the observations have been compared with an analytical decay model that accounts for both the increasing vertical thickness and the radial expansion of these pancake-like structures.

Introduction Outside of theoretical interest in their peculiar properties, one of the main motivations for understanding the dynamics of internal gravity waves is that they occur naturally in the atmosphere and oceans. In the atmosphere, through transporting horizontal momentum from the ground upwards, internal waves influence wind speeds and ...
