They also developed the idea of quantum vortex rings.
Theory of a vortex ring motion under gravity action.
In the 1960s, Rayfield andReif established the existence of quantized vortex rings.
Vortex ring is very often observed immediately after the certain explosions.
The flow direction along the generatrix of a vortex ring is determined by the pressure gradient.
The vortex ring is a vortex, which is closed into the annular solid of revolution.
The magnetized aether may support the helical vortex rings, including a very stable and self-contained.
The vortex is oriented by the torques,which arise in its external volume outside the vortex ring filament.
In any case, the vortex ring is a torus deformed in any way.
The real classified flying discs of the Third Reich were based on a non-trivial scheme,where the vortex ring was a principle in contrast with a conventional scheme.
The vortex ring is the only possible form of a stable vortex, which may not consume energy from the environment.
The evolution of acoustic radiation emitted by an ensemble of vortex rings in air is studied on the basis of nonstationary Navier-Stokes equations.
The vortex ring is the only possible form of a stable vortex, which may not consume the external energy.
Later Huang and Chan reported that if the initial state of the vortex ring is not perfectly circular, another kind of instability would occur.

As a result, the whole system contains a helical vortex ring of the moist air, which can cause a tornado effect under the certain conditions.
This creator, through the intermediate hierarchy, fills by the adapted"light" all the beings,who consist of the sephirot-vessels the same spherical vortex rings or chakras.
The working mass contains a vortex ring, where the aether is accelerated to the velocities, which approach the speed of light, producing a pressure of up to 1 MPa 10 dyn/cm 2.
To date, a number of models of this kind have been proposed, including:models with vortex rings, hard-sphere models, and Gaussian cluster theories.
One way a vortex ring may be formed is by injecting a compact mass of fast moving fluid(A) into a mass of stationary fluid(B) which may be the same fluid.
It is also very likely, although still very difficult to verify that at least in some cases, whether the most powerful orjust average lightning on the spot creates a vortex ring.
The magnetic machines could be analyzed and calculated easier,because they have only one stable helical vortex ring around the rotor with a density, which is specified by a flux density of the magnets.
Vortex rings were first mathematically analyzed by the German physicist Hermann von Helmholtz, in his 1858 paper On Integrals of the Hydrodynamical Equations which Express Vortex-motion.
A kind of azimuthal radiant-symmetric structure was observed by Maxworthy when the vortex ring traveled around a critical velocity, which is between the turbulence and laminar states.
But the turbine frequent blades, unlike the rare rotor blades-wings, produces a powerful descending air jet, which easily returns from the output back to the input due to the vertical pressure drop,forming a powerful vortex ring and significantly reducing the lift force.

It is possible to see that simultaneously is every such mushroom combined with a much faster sideways spreading vortex ring(supersonic speed), though less noticeable and perceptible.
Some recent studies have also confirmed the presence of a vortex ring during rapid filling phase of diastole andimplied that the process of vortex ring formation can influence mitral annulus dynamics.
An elliptical vortex ring undergoes an oscillation in which it is first stretched in the vertical direction and squeezed in the horizontal direction, then passes through an intermediate state where it is circular, then is deformed in the opposite way(stretched in the horizontal direction and squeezed in the vertical) before reversing the process and returning to the original state.
Comparing some of their shapes may suggest an idea that some of them would be created by a fairly complex set of vortex rings, moving over the ground in different directions, whose parts are displayed at certain moments in the structure of the crop.
