Density stratification due to temperature or salinity variations greatly influences the flow
around and the sedimentation of objects such as particles, drops, bubbles, and small …

Rigid or deformable bodies moving through continuously stratified layers or across sharp
interfaces are involved in a wide variety of geophysical and engineering applications, with …

Plastic pollution has been observed throughout the world's oceans and estuaries, whether
floating at the surface, settled in bottom sediments, washed up on beaches, or ingested by …

Marine snow aggregates are often a dominant component of carbon flux and are sites of
high bacterial activity; thus, small-scale changes in the settling behavior of marine snow can …

Stratification due to salt or heat gradients greatly affects the distribution of inert particles and
living organisms in the ocean and the lower atmosphere. Laboratory studies considering the …

We consider the unbounded settling dynamics of a circular disk of diameter becomes
smaller than some threshold value. Uncertainties in identifying the threshold value is …

Selected situations in which a rigid sphere settles through a two-layer system obtained by
superimposing two immiscible Newtonian fluids are studied using a combination of …

The settling velocity of porous particles in linear stratification is affected by the diffusive
exchange between interstitial and ambient water. The extent to which buoyancy and …

An extremely broad and important class of phenomena in nature involves the settling and
aggregation of matter under gravitation in fluid systems. Here, we observe and model …

Settling due to gravity force is a basic transport mechanism of solid particles in fluids in the
Earth. A large portion of particles occurring in nature and used in technical applications are …
