(Phys.org)—An airplane's vortex generators, which look like small fins on its surface, improve the plane's aerodynamics similar to the way in which the dimples on a golf ball improve the ball's ...

Toroidal pulses Air cannons produce visible vortex rings by generating rotating air pressure differences, while electromagnetic cannons emit electromagnetic vortex pulses using coaxial horn antennas. ...

Researchers are experimenting with reducing drag on trucks with electric wind devices that mimic the way vortex generators increase lift on airplane wings. Researchers in Sweden are experimenting with ...

The air in airliner cabins is typically kept very dry. It has to be, in order to stop condensation from accumulating within the plane. Unfortunately, this also dries out passengers' mucus membranes, ...
