In many arid regions, people use devices known as solar stills to extract drinkable water from seawater or tainted water. A new type of solar still is claimed to be much more effective than others, by ...

From stirring milk in your coffee to fearsome typhoon gales, rotating turbulent flows are everywhere. Yet, these spinning currents are as scientifically complex as they are banal. Describing, modeling ...

CURRENT interest in the removal of films of contaminants from water by rotating cylinders has prompted an investigation of the mechanism. Remarkable effects are observed when a small cylinder is ...

In this paper a new method is described for solving the characteristic value problem underlying the theory of the stability of viscous flow between rotating cylinders. The method depends on solving a ...

On 19 November 1924, a ship slowly manoeuvred through the Port of Kiel. On board were Ludwig Prandtl and Albert Betz from the Aerodynamic Research Institute (AVA) in Göttingen – a predecessor of today ...

A rotating black hole is such an extreme force of nature that it drags surrounding time and space around with it. So it is only natural to ask whether black holes could be used as some sort of energy ...

Connecting stationary piping to rotating tanks can put a strain on the joint between the two. The SX rotary joint from The Johnson Corp., Three Rivers, Mich. (joco.com), safely and reliably connects ...
