Vorticity, a measure of the local rotation or swirling motion in a fluid, has long been studied by physicists and mathematicians. The dynamics of vorticity is governed by the famed Navier-Stokes ...

If a drop of creamer falls from a spoon into a swirling cup of coffee, the whirlpool drags the drop into rotation. But what would happen if the coffee had no friction—no way to pull the drop into a ...

French researchers develop sophisticated mathematical model to study the behavior of earthly vortices, like hurricanes and ocean currents What do smoke rings, tornadoes and the Great Red Spot of ...

Scientists have exploited the properties of rotating fluids to build structures that could be used for applications in photonics. Many of the structures found in nature, such as strands of DNA and ...

A new experiment in wave turbulence achieves the long-sought goal of generating “pure” interacting waves that behave as theory predicts. Figure 1: In a rotating fluid, the predicted wave spectrum for ...

Scientists performed simulations of merging rotating superfluids, revealing a peculiar corkscrew-shaped mechanism that drives the fluids into rotation without the need for viscosity. If a drop of ...
