  3. Wingtip vortices - Wikipedia

    en.wikipedia.org/wiki/Wingtip_vortices

    Wingtip vortices are circular patterns of rotating air left behind a wing as it generates lift. [1] : 5.14 The name is a misnomer because the cores of the vortices are slightly inboard of the wing tips. [2] : 369 Wingtip vortices are sometimes named trailing or lift-induced vortices because they also occur at points other than at the wing tips.

  4. Vortex tube - Wikipedia

    en.wikipedia.org/wiki/Vortex_tube

    Vortex tube. The vortex tube, also known as the Ranque-Hilsch vortex tube, is a mechanical device that separates a compressed gas into hot and cold streams. The gas emerging from the hot end can reach temperatures of 200 °C (390 °F), and the gas emerging from the cold end can reach −50 °C (−60 °F). [1] It has no moving parts and is ...

  5. Vortex lift - Wikipedia

    en.wikipedia.org/wiki/Vortex_lift

    Vortex lift works by capturing 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 ...

  6. Vortex shedding - Wikipedia

    en.wikipedia.org/wiki/Vortex_shedding

    In fluid dynamics, vortex shedding is an oscillating flow that takes place when a fluid such as air or water flows past a bluff (as opposed to streamlined) body at certain velocities, depending on the size and shape of the body. In this flow, vortices are created at the back of the body and detach periodically from either side of the body ...

  7. Vorticity - Wikipedia

    en.wikipedia.org/wiki/Vorticity

    A vortex tube is the surface in the continuum formed by all vortex lines passing through a given (reducible) closed curve in the continuum. The 'strength' of a vortex tube (also called vortex flux ) [ 10 ] is the integral of the vorticity across a cross-section of the tube, and is the same everywhere along the tube (because vorticity has zero ...

  8. Rankine vortex - Wikipedia

    en.wikipedia.org/wiki/Rankine_vortex

    The Rankine vortex is a simple mathematical model of a vortex in a viscous fluid. It is named after its discoverer, William John Macquorn Rankine . The vortices observed in nature are usually modelled with an irrotational (potential or free) vortex. However, in potential vortex, the velocity becomes infinite at the vortex center.

  9. Vortex stretching - Wikipedia

    en.wikipedia.org/wiki/Vortex_stretching

    Vortex stretching is at the core of the description of the turbulence energy cascade from the large scales to the small scales in turbulence. In general, in turbulence fluid elements are more lengthened than squeezed, on average. In the end, this results in more vortex stretching than vortex squeezing. For incompressible flow —due to volume ...
