Vortex. Pathlines of fluid particles around the axis (dashed line) of an ideal irrotational vortex.
(See animation) Plughole Vortex In fluid dynamics, a vortex is a region within a fluid where the flow is mostly a spinning motion about an imaginary axis, straight or curved. That motion pattern is called a vortical flow.[1][2] (The original and most common plural of "vortex" is vortices,[3] although vortexes is often used too.[4]) Once formed, vortices can move, stretch, twist, and interact in complex ways. Properties[edit] Vorticity[edit] and expressed by the vector analysis formula , where is the nabla operator.[5] The local rotation measured by the vorticity must not be confused with the angular velocity vector of that portion of the fluid with respect to the external environment or to any fixed axis.
May be opposite to the mean angular velocity vector of the fluid relative to the vortex line. Vorticity profiles[edit] Irrotational vortices[edit] . On the Magnetic properties of superconductors of the second group. First vortex 'chains' observed in engineered superconductor. They look like tiny swirling dust devils on the surface of the superconductor: "vortices" that appear where magnetic fields interact with the material.
Unlike harmless dust devils, however, vortices can sap a superconductor's ability to transmit current without resistance.

The device can determine the surface structure of a sample at the atomic scale, leading to new discoveries about the interaction of magnetic fields and high-temperature superconductors.

View vortex video: Vortices, the small dark dots appearing in these video images (2 MB .mov file) from a scanning tunneling microscope, are where magnetic fields penetrate a superconductor and the amount of current the material can carry. A critical factor limiting applications for these superconductors is their response to magnetic fields, such as in electric motors. Source: Argonne National Laboratory. CHAKRA VORTEX , SCALAR ENERGY TRANSCEIVER. If you have never heard of the 7 chakras, you are indeed an ignoramus, of the first order.When my wife took her exam in Reiki, the old Guru gave her his quartz tetrahydron dowser , and told her to douse his body and find out which chakra of his body needs speeding up.
She found a weak Manipura , and thus got her 4th degree ( one step above Grandmaster ).Before that he took her to a room, with about 50 pictures of various dieties and saints, and told her that the energy would come to her chakras from only one of the pictures. To her surprise she felt it emanating in full force , from the photograph of a person she had always detested, since childhood-- a living person ( no names ! )-- and pointed it out . The Guru told her, she was right. My son at Cornell ( doing his ME in computer science ) will never take a tablet for headache, if he has one. Of course nowadays , the white man/ women gives his/her own take about chakras, with the British Stonehenge thrown in for good measure ( sic! Stargate - Vortex Based Mathematics.

Lamb–Oseen vortex. In fluid dynamics, the Lamb–Oseen vortex models a line vortex that decays due to viscosity.
This vortex is named after Horace Lamb and Carl Wilhelm Oseen.[1] Vector plot of the Lamb-Oseen vortex The mathematical model for the flow velocity in the circumferential –direction in the Lamb–Oseen vortex is: with The radial velocity is equal to zero. An alternative definition is to use the peak tangential velocity of the vortex rather than the total circulation where is the radius at which is attained, and the number α = 1.25643, see Devenport et al.[2] Vortex.
