Vortices In Nature Affected By Earth's Rotation
2013-10-15 13:59:58

[ Watch The Video: Radiative Instability of a Geophysical Vortex ] American Institute of Physics French researchers develop sophisticated mathematical model to study the behavior of earthly vortices, like hurricanes and ocean currents What do smoke rings, tornadoes and the Great Red Spot of Jupiter have in common? They are all examples of vortices, regions within a fluid (liquid, gas or plasma) where the flow spins around an imaginary straight or curved axis. Understanding how...

Earth's Ocean Eddies Are Mathematically Similar To Black Holes In Space
2013-09-23 14:42:00

[ Watch the Video: Common Thread Between Black Holes And Ocean Eddies ] Lee Rannals for redOrbit.com - Your Universe Online Scientists at the Eidgenössische Technische Hochschule and University of Miami found that some of the largest ocean eddies on Earth are quite similar to the mysterious black holes of space. An ocean eddy is the swirling of a fluid and the reverse current created when the fluid flows past an obstacle. Our climate has influenced huge ocean eddies over 90-miles in...

Two Vortices Seen Circling Newborn Tropical Storm Man-yi's Center
2013-09-13 15:16:36

NASA NASA's Terra satellite passed over newborn Tropical Storm Man-yi and captured and image that clearly showed two vortices rotating around a large center of circulation. Man-yi formed on Sept. 12 in the northwestern Pacific Ocean as the sixteenth tropical depression and by Sept. 13 it strengthened into a tropical storm. When NASA's Terra satellite passed over newborn Tropical Storm Man-yi in the northwestern Pacific Ocean on Sept. 13 at 01:15 UTC, the Moderate Resolution Imaging...

Zombie-Like Vortex Gives Final Push To Birth New Star
2013-08-21 14:06:17

Brett Smith for redOrbit.com - Your Universe Online For years, most astronomers have agreed on the basic steps that lead to star formation, except one – how a cloud of swirling gas can slow down enough to concentrate into something capable of nuclear fusion. A new study from the University of California, Berkeley has found evidence of “zombie vortices” within a gestating star leading to a final push that gives birth to a new star. According to prevailing theories, stars begin...

Turbulence is all around us—in the patterns that natural gas makes as it swirls through a transcontinental pipeline or in the drag that occurs as a plane soars through the sky. Reducing such turbulence on say, an airplane wing, would cut down on the amount of power the plane has to put out just to get through the air, thereby saving fuel. But in order to reduce turbulence—a very complicated phenomenon—you need to understand it, a task that...

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...

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...
