The study of vortex ring dynamics centres on understanding the formation, evolution and decay of toroidal vortices generated by pulsed fluid jets. These phenomena are crucial in a wide range of ...

Vortex rings are pretty cool, and electromagnetism even cooler. Now, a team of physicists have found a way to combine the two phenomena, creating the electromagnetic vortex cannon. In fluids ...

The gun forms vortex rings by forcing air or some other gas at high velocity down the gun’s cylinder. The ring forms when the friction of the cylinder wall causes a thin layer of the gas to roll ...

Rather, the velocity of a sneeze, as well as temperature differences in the air, can cause the droplets to form what scientists call a "sneeze vortex," or vortex rings.

Vortex guns work by forcing air or another gas at a high velocity, down the inside of a cylinder. Friction along the inside of that cylinder wall slows down a thin layer of that flowing gas ...

Akagi’s team did computer simulations of the airflow surrounding a person wearing a popular design of face shield. The person is exposed to the sneeze of a person standing 1 m in front of them. The ...

Vortex loops are common phenomena, showing up in not only smoke rings but mushroom clouds, fire-eater tricks, and even the sun's outer atmosphere, the corona. A big question was what happens to ...

Face shields no match for sneeze vortex rings Face shields worn alone are not effective against COVID-19 sneezes Date: December 8, 2020 Source: American Institute of Physics ...

It takes 20 kts. of headwind in a medium disk loading because the induced velocity from the rotor disk is stronger. Once the trim string rises steadily, the helicopter is outside of the VRS envelope.
