English
vortex, vertex, -icis, fr. vortere, vertere, to turn. See {Vertex}.] [1913 Webster] 1. A mass of fluid, especially of a liquid, having a whirling or circular motion tending to form a cavity or vacuum in the center of the circle, and to draw in towards the center bodies subject to its action; the form assumed by a fluid in such motion; a whirlpool; an eddy. [1913 Webster] 2. (Cartesian System) A supposed collection of particles of
very subtile matter, endowed with a rapid rotary motion
around an axis which was also the axis of a sun or a
planet. Descartes attempted to account for the formation
of the universe, and the movements of the bodies composing
it, by a theory of vortices.
[1913 Webster]
3. (Zo"ol.) Any one of numerous species of small
Turbellaria belonging to {Vortex} and allied genera. See
Illustration in Appendix.
[1913 Webster]
Vortex atom (Chem.), a hypothetical ring-shaped mass of
elementary matter in continuous vortical motion. It was
conveniently regarded in certain early mathematical models
as the typical form and structure of the chemical atom,
but is no longer considered a useful model, having been
superseded by quantum mechanics.
Vortex wheel, a kind of turbine.
[1913 Webster +PJC]
Vortex filament Vor"tex fil"a*ment
A vortex tube of infinitesimal cross section.
[Webster 1913 Suppl.]
Vortex fringe Vor"tex fringe
The region immediately surrounding a disk moving flatwise
through air; -- so called because the air has a cyclic motion
as in vortex ring.
[Webster 1913 Suppl.]
Vortex line Vortex line
A line, within a rotating fluid, whose tangent at every point
is the instantaneous axis of rotation as that point of the
fluid.
[Webster 1913 Suppl.]
Vortex ring Vortex ring (Physics)
A ring-shaped mass of moving fluid which, by virtue of its
motion of rotation around an axis disposed in circular form,
attains a more or less distinct separation from the
surrounding medium and has many of the properties of a solid.
[Webster 1913 Suppl.]
Vortex theory Vortex theory (Chem. & Physics)
The theory, advanced by Thomson (Lord Kelvin) on the basis of
investigation by Helmholtz, that the atoms are vortically
moving ring-shaped masses (or masses of other forms having a
similar internal motion) of a homogeneous, incompressible,
frictionless fluid. Various properties of such atoms (
vortex atoms) can be mathematically deduced. This theory is
now (1998) obsolete, and has been superseded by quantum
mechanics, which provides more accurate and detailed
explanations of atomic behavior.
[Webster 1913 Suppl. +PJC]
Vortex tube Vortex tube (Physics)
An imaginary tube within a rotating fluid, formed by drawing
the vortex lines through all points of a closed curve.
[Webster 1913 Suppl.]
