The vortex tube, also known as the Ranque-Hilsch vortex tube, is a mechanical device that separates a compressed gas into hot and cold streams. The gas emerging from the hot end can reach temperatures of 200 °C (390 °F), and the gas emerging from the cold end can reach −50 °C (−60 °F). [ 1 ]
The Tornado Tube is a device made of molded plastic that can be used to connect two two-liter soda bottles. When one of the bottles is filled with liquid and the two bottles are connected with a Tornado Tube, they may be used as a children's educational toy demonstrating a vortex.
Airless tires are often filled with compressed polymers (plastic) rather than air, or can be a solid molded product. Airless tires are attractive to cyclists, as bicycle tires are much more vulnerable to punctures than motor vehicle tires. The drawbacks to airless tires depend on the use.
In general, vortex lines (in particular, the axis line) are either closed loops or end at the boundary of the fluid. A whirlpool is an example of the latter, namely a vortex in a body of water whose axis ends at the free surface. A vortex tube whose vortex lines are all closed will be a closed torus-like surface. A newly created vortex will ...
When you think of a vending machine, things like snacks, sodas, or even pharmaceutical supplies may come to mind. But you might be surprised to know that the first ever vending machine actually ...
A tubeless tire (also spelled as tubeless tyre in Commonwealth English) is a pneumatic tire that does not require a separate inner tube.. Unlike pneumatic tires which use a separate inner tube, tubeless tires have continuous ribs molded integrally into the bead of the tire that are forced by air pressure into a flange on the metal rim of the wheel, sealing the tire to the rim.
An inner tube is an inflatable torus that forms the interior of some pneumatic tires. [1] The tube is inflated through a valve stem and fits inside the tire casing. The inflated inner tube provides structural support and suspension, while the outer tire offers grip and protects the more fragile tube.
A vortex tube is the surface in the continuum formed by all vortex lines passing through a given (reducible) closed curve in the continuum. The 'strength' of a vortex tube (also called vortex flux ) [ 10 ] is the integral of the vorticity across a cross-section of the tube, and is the same everywhere along the tube (because vorticity has zero ...
