The following article is from The Great Soviet Encyclopedia (1979). It might be outdated or ideologically biased.



independent fluctuations of the surface of the ocean or sea during a complete calm, consisting of long and sloping waves up to 10–15 m high and 300–400 m long and with phases of up to 17–20 sec. They result from the conversion of wind waves during their departure from an area of wind activity or after the dying down of winds. Waves of a swell are nearly indistinguishable in terms of size and shape. Particles of water in such waves move in regular circular orbits.

The volumetric increase of soils on being removed from their compacted beds due to an increase in void ratio.
A local enlargement or thickening in a vein or ore deposit.
A low dome or quaquaversal anticline of considerable areal extent; long and generally symmetrical waves contribute to the mixing processes in the surface layer and thus to its sound transmission properties.
Gently rising ground, or a rounded hill above the surrounding ground or ocean floor.
(mining engineering)
Ocean waves which have traveled away from their generating area; these waves are of relatively long length and period, and regular in character.

(9) have studied viscoelastic flow simulations of various extrudate swells by the Giesekus model (10), which is one of the differential-type constitutive equations.
It is important to understand the swell behavior of polymer melts because the parison shape, that is, the thickness and the diameter, changes dramatically as a result of swelling, and the swell behavior seriously depends on material properties or die dimensions.
Standard practice to achieve proper belt gauge has been to start with an opening that is too small, to run a die trial, and to recur the die assuming the die swell extrudate expansion will remain the same in each zone.
The parison formation process is, however, difficult to predict because of unsteady viscoelastic flow, including the effects of extrudate swell, drawdown, and shrink-back.
As alluded to above, a polymer network with a large value of [M.sub.c] is able to swell to a higher degree than that of a network having a lower value of [M.sub.c].
The big difference of this lateral unconfined uniaxial swelling test from the swelling test of conventional consolidation equipment lies in the fact that the rock samples can swell freely during the process of their hydrated swelling without any lateral confinement.
Therefore, uncured EPDM can be dissolved and the cured EPDM swells in diesel fuel.
Because the groups are bound to the material, they can't move far apart, but they can force the material to swell, says Lee.
So when the parison drops, small variations in horizontal position caused by variations in die swell, parison swinging, or parison air pressure do not have as much effect on processing.
I tried to figure out how big the swells were, which way the wind was blowing, and where the waves were breaking.
Swells are--that form way out in the middle of the ocean.
When reproductive organs shift (or the prostate swells), this can constrict normal flow of blood, lymph, and nerve connections.
