The particles were 3D printed into a shape like a hockey puck—each was approximately 1 centimeter in diameter. The particles were hollow, making them buoyant.

The term “granular flows” refers to a system of solid particles in which the flow behavior is dictated solely by particle-particle and particle-wall interactions (i.e., the role of the interstitial ...

Kelvin waves have been a mystery for decades but a new method involving superfluid helium-4 can help us control them.

and the number of particles released simultaneously, according to a new paper published in the journal Physics of Fluids. We've previously reported on physicists' longstanding interest in similar ...

Non-Newtonian fluids are solid if you apply a sudden force and liquid if you apply a steady, slow force. How can something be a solid and a liquid? In the mix, there are tiny cornstarch particles ...

The movement and space between particles in a fluid affects the amount of pressure the fluid exerts. This means that the pressure in a fluid changes depending on its height, depth and temperature.

When particles reach the bottom rapidly ... Morphology of particle cloud deposits, Physics of Fluids (2025). DOI: 10.1063/5.0239386 ...
