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 ...

Conceptual diagram of the influence of horizontal vortex tubes on tornado genesis and development during the intensification stage: (a) the effect of horizontal vortex tubes on tornado rotation; (b) ...

Vortex tubes are a key ingredient of turbulence, which is widely studied in classical physics. The motion of vortex tubes is relevant in a wide range of scenarios, such as the formation of hurricanes, ...

Rather than building ever-larger Coriolis, vortex or ultrasonic sensors, engineers can use smaller measuring paths and combine their outputs to accurately measure flow in large-diameter pipelines.

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 ...
