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 ...

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.

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 ...

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