As this vortex lies beside and behind the wing, it does not contribute to lift. The delta traps this over the rear surface of the wing and uses it for lift. Vortex lift is a form of lift force lift generated by delta wing s operating at high angle of attack angles of attack . How it works Vortex lift works by capturing vortex vortices generated from the sharply swept leading edge of the wing. The vortex, formed roughly parallel to the leading edge of the wing, is trapped by the airflow and remains fixed to the upper surface of the wing. As the air flows around the leading edge, it flows over the trapped vortex and is pulled in and down to generate the lift. Advantages and disadvantages The major advantage of vortex lift is that it allows angles of attack that would Stall flight stall a normal wing. Since it does not require camber aerodynamics camber to generate lift, but does require significant sweep back, vortex lift is utilized by most supersonic aircraft for landing the characteristic bending nose of the commercial Concorde was built to allow the pilots to see over the nose during landing, when the aircraft was at a very high angle of attack. The disadvantage of vortex lift is the Drag physics drag that it produces. Vortices are a primary cause of drag in most aircraft, and the large vortices generated when using vortex lift cause correspondingly high drag. This high drag can actually be considered advantageous during ... DEFAULTSORT Vortex Lift Category Aerodynamics Category Vortices Aviation stub ko pl No no ... more details

It consists of an electric motor with the drive shaft oriented vertically and attached to a cupped rubber piece mounted slightly off center. As the motor runs the rubber piece oscillates rapidly in a circular motion. When a test tube or other appropriate container is pressed into the rubber cup or touched to its edge the motion is transmitted to the liquid inside and a vortex is created. Most vortex mixers have variable speed settings and can be set to run continuously, or to run only when downward pressure is applied to the rubber piece. Vortex mixers are quite commonplace in bioscience laboratories. In cell culture and microbiology laboratories they may be used to suspension chemistry suspend cells. In a biochemistry biochemical or analytical chemistry analytical laboratory they may be used to mix the reagent s of an assay or to mix an experimental sample and a dilutant . The vortex mixer was invented by the Kraft brothers Jack A. Kraft and Harold D. Kraft while working for Scientific Industries a laboratory equipment manufacturer . A patent was filed by the Kraft brothers on April 6, 1959 and granted on October 30, 1962 US patent 3,061,280 . Scientific Industries still makes a version of this original vortex mixer.

No footnotes date April 2009 In superconductivity , a Josephson vortex after Brian David Josephson Brian Josephson from Cambridge University is a vortex of supercurrent in a long Josephson junction LJJ . The supercurrents circulate around the vortex center which is situated inside the Josephson barrier. In contrast to Abrikosov vortex Abrikosov vortices in type II superconductors , a Josephson vortex has no normal core . Usually the Josephson vortex s supercurrents create a magnetic field with the total flux equal to math Phi 0 math &mdash a magnetic flux quantum single flux quantum . Such a vortex is therefore called a Josephson fluxon . It has been shown that under certain conditions a propagating Josephson vortex can initiate another Josephson vortex. This effect is called flux cloning or fluxon cloning . Although a second vortex appears, this does not violate the conservation of the single flux quantum. Recently When date February 2011 it was demonstrated by Hilgenkamp et al. that Josephson vortices in the so called 0 &pi LJJ can also carry half of the magnetic flux quantum flux quantum , and are called semifluxon s.

The horseshoe vortex model is a simplified representation of the vortex system of a wing . In this model the wing vorticity is modelled by a bound vortex of constant Circulation fluid dynamics circulation , travelling with the wing, and two Wingtip vortices trailing vortices , therefore having a shape vaguely reminiscent of a horseshoe. ref Millikan, Clark B., Aerodynamics of the Airplane , Figure 1.35 ref ref McCormick, Barnes W., Aerodynamics, Aeronautics, and Flight Mechanics , Chapter 3 ref The starting vortex created as the wing begins to move through the fluid is considered to have been dissipated by the action of viscosity , as are the Wingtip vortices trailing vortices well behind the aircraft. The Wingtip vortices trailing vortices are responsible for the component of the downwash which creates induced drag . ref McCormick, Barnes W., Aerodynamics, Aeronautics, and Flight Mechanics , Chapter 4 ref The horseshoe vortex model is unrealistic in implying a constant Circulation fluid dynamics circulation and hence by the Kutta Joukowski theorem constant lift at all sections on the wingspan . In a more realistic model due to Ludwig Prandtl the vortex strength reduces along the wingspan , and the loss in vortex strength is shed as a vortex sheet from the trailing edge, rather than just at the wing tips. ref McCormick, Barnes W., Aerodynamics, Aeronautics, and Flight Mechanics , Figure 4.21 ref However, by using the horseshoe vortex model with a reduced ... more details

The key similarity is that they are both ... up of each quantum vortex is neither superfluid nor superconductor, for each system. In a superfluid, a quantum vortex carries the angular momentum , thus allowing the superfluid to rotate in a superconductor , the vortex carries the magnetic flux . Vortex in a superfluid In a superfluid, a quantum vortex is a hole with the superfluid circulating around the vortex the inside of the vortex may contain excited particles, air, vacuum, etc. The thickness of the vortex depends upon the chemical ... that is an absence of superfluid, for example a rod through the superfluid or a vortex, then the circulation ... is the mass of the superfluid particle, and math Delta phi math is the phase difference around the vortex ... the vortex similar to what is described in the Bohr model , then math Delta phi 2 pi n math , where ... mathbf l frac 2 pi hbar m n. math Vortex in a superconductor A principal property of superconductors ... cases, it may be energetically favorable for the superconductor to form a quantum vortex, which ... state prevails in the regions around the vortex.

The remainder of the gas is forced to return in an inner vortex of reduced diameter within the outer vortex. There are different explanations for the effect and there is debate on which explanation ... as that of the outer gas. This is different from what most consider standard vortex behavior where ... to the long time which each parcel of air remains in the vortex allowing friction between the inner ... angular velocity and direction, the inner vortex has lost angular momentum . The decrease of angular momentum is transferred as kinetic energy to oddly the outer vortex, resulting in separated flows of hot and cold gas. ref http www.exair.com Cultures en US Primary Navigation Products Vortex Tubes and Spot Cooling Vortex Tubes A Phenomenon of Physics exair.com Vortex tube theory ref This is somewhat ... , heat sinking the whole vortex tube is helpful.
