The subject of vortices might seem esoteric. But their impact does make headlines, as seen recently in an outbreak of tornadoes, swirling vortices that killed at least 80 people across eight U.S.

Pore-scale mechanisms of drag reduction by micro-blowing have rarely been explored. A direct numerical simulation (DNS) study ...

Knots are not just for shoelaces and sailing lines. In the last decade, physicists have shown that swirling liquids can ...

Turbulent ball: William Irvine, Takumi Matsuzawa and colleagues have used this apparatus to track turbulence with lasers and high-speed cameras. (Courtesy: Takumi Matsuzawa) Researchers in the US have ...

You don’t have to live near Hoover Dam to tap hydropower. Experts at Belgium’s Turbulent have developed a Vortex turbine that maximizes low-flow water from rivers and canals that also have low height ...

There was once a saying from the renowned American physicist Richard Feynman about turbulence. He said that it remains to be the most important "unsolved" problem in classical physics. The challenge ...

Every airplane creates wake turbulence while in flight, which results in two counter-rotating vortices trailing behind the aircraft. These vortices can affect other aircraft as it passes. According to ...

SAE Transactions, Vol. 114, SECTION 6: JOURNAL OF PASSENGER CAR: MECHANICAL SYSTEMS JOURNAL (2005), pp. 612-624 (13 pages) Recent results are presented from the application of a grid-free vortex ...

Helicopter safety researchers are to undertake formal analysis of the hazardous vortex ring phenomenon and the effectiveness of an alternative recovery and escape technique. The vortex ring state is ...
