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 ...

When people are thinking of the future of space travel, an idea that floats around is a spaceship with a giant solar sail pushed along by a massive laser. Inspired by the concept but lacking a giant ...

Vortex tubes provide a low-cost, maintenance-free solution to industrial spot-cooling problems Vortex tubes provide a low-cost, maintenance-free solution to industrial spot-cooling problems. Using the ...

High-temperature vortex tubes convert compressed air into two streams: one hot, one cold. The tubes cool applications up to 392°F (200°C). The devices produce cold air down to –50°F (–46°C) and have a ...
