Physics Fluid dynamics

Researchers analyze the collapse of the Misasa Railroad Bridge in Japan — an infrastructure failure caused by unprecedented flooding back in 2018 — to inform future flood-resistant designs.

By virtually reproducing physical reservoir computing, a new information processing technology, using numerical simulation, the present study reveals that vortices in fluid flow phenomena in the downstream region of a cylinder are the key to information processing capability. It is expected that this result concerning fluid flow vortices and information processing capability will be useful in enhancing the information processing capability of the physical reservoir using fluid flow.

New microscopy technique provides unprecedented insight into nanoscopic slip layers formed in flowing complex liquids.

Ultrafast video capture of droplet cloud formation should help minimize the risk of gas-leak explosions.
