Added mass for motion in density-stratified fluidsBruno Voisin7th Euromech Fluid Mechanics Conference
When a source of variable intensity moves in a stratified fluid, several types of waves, possibly including waves that outstrip the source (precursor waves), are generated. By analyzing the expressions for the mean energy losses due to internal wave radiation per unit time it is shown that in...
The density of the air in the atmosphere, or of the water in the ocean, is a function of altitude or depth. Linear equations for the motion of such stratified fluids have been derived by many authors. Many have introduced simplifying assumptions into their derivations, with the result that ...
Solitary internal waves in deep water A new type of solitary wave motion in incompressible fluids of non-uniform density has been investigated experimentally and theoretically. If a fluid is stratified in such a manner that there are two layers of different density joined by... RE Davis,A Acri...
Direct numerical simulations of a swarm of deformable drops rising in density stratified fluids are presented at intermediate Reynolds numbers. All flow scales are fully resolved using front-tracking/finite-volume method. The average rise velocity and velocity fluctuations of the swarm are reduced in ...
Abstract Adjustment of unbalanced vortices in uniformly rotating and stratified fluids (th Conference on Atmospheric and Oceanic Fluid Dynamics)
These parameters depend on the surface roughness, and in a stratified fluid they also depend on the stability of the stratification; for example, in very stable conditions, Ca ≈ 10− 4 and θa≈ 35 degrees while in unstable conditions Ca ≈ 1.5 × 10− 3 and θa → 0. The sea ...

This flow pattern occurs when waves of a stratified liquid layer grow to reach the top of the pipe and the gas propels a `slug' of liquid along the pipe. The resulting flow pattern consists of a series of liquid slugs separated by bubbles that occupy almost the entire pipe cross-section...
