vortex street

These vortices are unstable and a vortex street is developed.

However, this leads to a symmetric vortex street pattern, unlike the ones shown above.

The wake of an obstacle in the flow may develop a Kármán vortex street.

Those cloud formations are known as von Kármán vortex streets.

The harp is driven by the von Kármán vortex street effect.

Vortex streets driven by sheared flow and applications to black aurora", Geophys."

These oscillations are called a Von Karman vortex street.

Thus the wake region is unstable and breaks up into a Von Karman vortex street.

The following is a list of islands and mountains worldwide known to cause the Von Kármán vortex street.

A repeating pattern of swirling vortices is named after him, the von Kármán vortex street.

Examples of global modes in practice include the oscillatory wakes produced when fluid flows past an object, such as a vortex street.

Another effect of boundary layer separation is shedding vortices, known as Kármán vortex street.

He liked the idea of each of the collaborators titling their contributions, and called his "Vortex Street".

It is an active island in generating the phenomenon, with a vortex street appearing almost every day in June to August.

The pitching motion around quarter-chord axis with triangular wave, however, could realize more easily the thrust producing vortex street.

Remote sensing observations: An analysis of a vortex street downstream of an obstacle in an estuarine flow.

However as the Reynolds number is increased the flow becomes asymmetric and the so-called Kármán vortex street occurs.

Many natural patterns are shaped by this apparent randomness, including vortex streets and other effects of turbulent flow such as meanders in rivers.

When, after a cycle, the trailing edge reverses direction the vortex is either shed in a vortex street or annihilated.

For example, the vortex street behind a stick underwater might radiate at audible frequencies but not sufficiently to be heard by a Scuba diver.

See Von Kármán vortex street.

NASA describes how this von Karman vortex street may have formed:

The wake behind the flap is a pair of counter-rotating vortices that are alternately shed in a von Kármán vortex street.

Kuril Islands, about 75% of the islands exhibit a vortex street, usually in the summer from June to August under low fog.
