Anyone who has drained a bathtub or stirred cream into coffee has seen a vortex, a ubiquitous formation that appears when fluid circulates. But unlike water, fluids governed by the strange rules of ...

An Australian-led study has provided new insight into the behaviour of rotating superfluids. A defining feature of superfluids is that they exhibit quantised vortices – they can only rotate with one, ...

Osaka Metropolitan University scientists investigated numerically the interaction between a quantized vortex and a normal fluid. Based on the experimental results, researchers decided the most ...

Vortex dynamics encompasses the study of rotating fluid structures that span scales from centimetre-sized eddies in engineering applications to kilometre-scale systems in the atmosphere and oceans.

Active colloidal fluids exhibit spontaneous emergence of correlated states, characterized by complex collective dynamics and self-organization. In geometrically confined systems, activity modulations ...
