In civil engineering (specifically hydraulic engineering), a hydrodynamic separator (HDS) is a stormwater management device that uses cyclonic separation to control water pollution. They are designed as flow-through structures with a settling or separation unit to remove sediment and other pollutants. [ 1 ]
[citation needed] For efficient separation, the density difference between the heavy minerals and the light minerals in the feedstock should be at least 1 g/cm 3; [1] and because the separation is dependent upon size and density, spiral separators are most effective at purifying ore if its particles are of uniform size and shape. A spiral ...
Hydrodynamic trapping can also be used to trap and study molecules in lipid bilayers. This is done using hydrodynamic drag forces that are created by a fluid flow through a very small cone shaped pipet located about one micrometer away from the lipid bilayer. This allows particles protruding from the lipid bilayer to be trapped and studied. [4]
In fluid dynamics, flow separation or boundary layer separation is the detachment of a boundary layer from a surface into a wake. [1] A boundary layer exists whenever there is relative movement between a fluid and a solid surface with viscous forces present in the layer of fluid close to the surface. The flow can be externally, around a body ...

At times, it seems the trouble that cats get into is entirely accidental. I can forgive my cat’s near-daily scattering of litter outside their box due to super-enthusiastic waste-burial techniques.

One design brings the water in the top of a container through a "header" which distributes the water evenly. The filter "media" start with fine sand on the top and then becomes gradually coarser sand in a number of layers followed by gravel on the bottom, in gradually larger sizes.
