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 ...

Large-eddy simulations provide a new view into how to produce and study vortices with a central eye and eye wall inside a ...

Rotating boundary layer dynamics is a critical field within fluid mechanics that addresses the behaviour of fluid layers adjacent to rotating surfaces. The interplay of centrifugal forces, Coriolis ...

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 ...

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 ...

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 ...
