Physicists working in the nascent field of experimental vortex dynamics have, with unexpected help from a Sharpie marker, measured an elusive but fundamental property of fluid flow. University of ...

Vortex dynamics in cylindrical containers encapsulate a range of complex fluid behaviours driven by rotational motion. In these geometries, the interplay between centrifugal forces and viscous effects ...

The Ranque-Hilsch vortex tube is an innovative device that utilises compressed gas to separate energy streams into distinct hot and cold outputs. Its operation is based on complex internal flow ...

Vortex dynamics simulations reveal reconnection, an important property linked with creation of turbulence cascade, fluid mixing, and aerodynamic noise generation. Turbulent pipe flow simulated at high ...

Liutex is a new physical quantity discovered by Chaoqun Liu et al at University of Texas at Arlington (UTA) in 2018 to describe fluid rotation, which is same important as velocity, pressure, ...
