A vortex tube splits a stream of air into hot and cold! This is how it works and why it doesn't violate the second law of thermodynamics.

One of the most widely accepted explanation of the Vortex Tube Phenomenon is that compressed air enters the tube's vortex spin chamber where it is transformed into a mini-tornado spinning at up to ...

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 ...

The Ranque-Hilsch vortex tube is an innovative device that utilises compressed gas to separate energy streams into distinct hot and cold outputs. Its operation is based on complex internal flow ...

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, ...

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 ...

Researchers have managed to visualize the vortex tubes in a quantum fluid, findings that could help researchers better understand turbulence in quantum fluids and beyond. Nobel laureate in physics ...

Vortex tubes provided a maintenance-free solution to a variety of industrial spot-cooling problems. Independent laboratory tests certify that the tubes meet safety, health, and environmental standards ...

We’re fascinated by things with no moving parts or active components that work simply by virtue of the shape they contain — think waveguides and resonators for microwave radiation. A similarly ...
