Analyzing New Vortical Flows Over A 76/40 Double Delta Wing Using Detached-eddy Simulations
2013-06-28 14:34:48

Science China Press The double delta wing is a simplified configuration used for studying aircraft aerodynamics. It is composed of a highly-swept delta wing connected in front of the main delta wing with a smaller sweep, reflecting the combination of a leading edge extension and the swept main wing. The aerodynamic performance of such wings, which includes the behavior of the leeside vortical flows at moderate and high angles of attack (AoA) at low speed, is of research interest. The...

Vortex Knot Created By Physicists
2013-03-04 12:29:46

University of Chicago [ Watch The Video Tying a Vortex Ring into a Knot ] University of Chicago physicists have succeeding in creating a vortex knot–a feat akin to tying a smoke ring into a knot. Linked and knotted vortex loops have existed in theory for more than a century, but creating them in the laboratory had previously eluded scientists. Vortex knots should, in principle, be persistent, stable phenomena. "The unexpected thing is that they're not," said Dustin Kleckner, a...

The Mysteries Of Hummingbird Flight
2013-02-26 05:40:07

[ Watch the Video: Hummingbird Hovering ] April Flowers for redOrbit.com - Your Universe Online The wings of the hummingbird move so fast — about 80 beats per second — these amazing creatures can actually fly right, left, up, down, backwards and even upside down. Until now, scientists believed the bird's remarkable flight generated a single trail of vortices in its wake that helps the bird hover. A research team, led by the University of California, Riverside, conducted...

Electron Beams That Possess An Inner Rotation Created
2012-11-05 13:28:11

Vienna University of Technology Vortex beams, rotating like a tornado, offer completely new possibilities for electron microscopy. A method of producing extremely intense vortex beams has been discovered at the Vienna University of Technology (TU Vienna). Nowadays, electron microscopes are an essential tool, especially in the field of materials science. At TU Vienna, electron beams are being created that possess an inner rotation, similarly to a tornado. These "vortex beams" cannot only...

A Vortex (plural: vortices) is a spinning, often turbulent, mass of flowing fluid. Any spiral movement with a closed streamline is considered vortex flow. The speed and rate of rotation of a vortex is always greatest at the center, with progressively decreasing speed away from the center. The fluid pressure is lowest in the center of the vortex, and rises further from the center (Bernoulli's Principle). The core of a vortex is sometimes visible due to a plume of water vapor caused by...

Turbulence (or turbulent flow) is characterized by chaotic, random property changes. Turbulence occurs with low momentum diffusion (spreading of atmospheric properties), high momentum convection (vertical transference of atmospheric properties), and rapid variation of pressure and velocity in both space and time. A flow that is not turbulent is known as laminar flow. A vortex moving at low speeds will most likely cause laminar flow, and as speeds increase a transition is made to turbulent...
