Visualisation of the vortex street behind a circular cylinder in air; the flow is made visible through release of glycerol vapour in the air near the cylinder. In fluid dynamics, a Kármán vortex street (or a von Kármán vortex street) is a repeating pattern of swirling vortices, caused by a process known as vortex shedding, which is responsible for the unsteady separation of flow of a fluid ...
Vortex shedding as winds pass Heard Island (bottom left) in the southern Indian Ocean resulted in this Kármán vortex street in the clouds 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 ...
Vortex created by the passage of an aircraft wing, revealed by colored smoke Von Karman vortex street behind a drinking straw. Milk was poured into the water to make the current visible. A Kármán vortex street is demonstrated in this photo, as winds from the west blow onto clouds that have formed over the mountains in the desert. This ...
A Von Karman vortex can't just occur anywhere, though. "The areas in the world where these conditions are most frequently encountered are the regions of the Trade Winds," Nicholls said.
In physics, physical chemistry and engineering, fluid dynamics is a subdiscipline of fluid mechanics that describes the flow of fluids – liquids and gases.It has several subdisciplines, including aerodynamics (the study of air and other gases in motion) and hydrodynamics (the study of water and other liquids in motion).
The polar vortex is a whirling cone of low pressure over the poles that's strongest in the winter months due to the increased temperature contrast between the polar regions and the mid-latitudes ...
A von Kármán vortex street. A Kármán vortex sensor works by disrupting the air stream with a perpendicular bow. Providing that the incoming flow is laminar, the wake consists of an oscillatory pattern of Kármán vortices. The frequency of the resulting pattern is proportional to the air velocity.
Satellites captured a beautiful phenomenon called Von Karman clouds off the coast of Mexico on May 8, and this occurrence has many wondering why and how these swirls are appearing over the Pacific ...
