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 ...

Dr. Julien's primary areas of research are in the dynamics and instability processes in geophysical and astrophysical fluid dynamics. These include turbulent fluid convection and the effects 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 ...

What do smoke rings, tornadoes and the Great Red Spot of Jupiter have in common? They are all examples of vortices, regions within a fluid (liquid, gas or plasma) where the flow spins around an ...

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 ...

Black hole in a blender: The experimental set-up the researchers used to create the giant quantum vortex, which mimics certain behaviours of black holes. (Courtesy: Leonardo Solidoro) A novel ...

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 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 ...
