There are two main types of fluid flow - laminar flow, in which the fluid flows smoothly in layers, and turbulent flow, which is characterised by chaotic motion and large amounts of mixing. In this ...

Scientists have uncovered evidence of classic turbulence occurring within swarms of rising gas bubbles. An international team of scientists from the (HZDR), Johns Hopkins University, and Duke Universi ...

From Quanta Magazine (find original story here). Spaghetti-thin shoelaces, sturdy hawsers, silk cravats—all are routinely tied in knots. So too, physicists believe, are water, air and the liquid iron ...

A body moving through a fluid experiences a drag force, which is usually divided into two components: frictional drag, and pressure drag. Frictional drag comes from friction between the fluid and the ...

The many applications of flow measurement include uses in water supply, medical research, oil exploration, food processing and distribution of gas. The uses of this technology are very diverse, with ...

Testing a total artificial heart To observe real-time blood flow in an artificial heart in the MRI, researchers at Linköping University built a full-scale model of the human circulatory system.

This week marked Vincent van Gogh's 162nd birthday. The always-illuminating Maria Popova celebrated in her Brainpickings newsletter by bringing back studies linking van Gogh's celebrated 1889 painting ...
