It’s long been accepted that the smoother the surface, the lower the aerodynamic drag. That turns out not always to be the ...

While atmospheric turbulence is a familiar culprit of rough flights, the chaotic movement of turbulent flows remains an unsolved problem in physics. To gain insight into the system, a team of ...

A sneeze. Ocean currents. Smoke. What do these have in common? They’re instances of turbulence: unpredictable, chaotic, uneven fluid flows of fluctuating velocity and pressure. Though ubiquitous in ...

Turbulence, famously described by Richard Feynman as “the last unsolved problem of classical physics”, pervades almost all natural and engineering flows. The century-old challenge of turbulence ...

You probably know the feeling: you’re sitting on a plane, happily cruising through the sky, when suddenly the seat-belt light comes on and things get a little bumpy. Most of the time, turbulence leads ...
