(Phys.org) —Anyone who has flown in an airplane knows about turbulence, or when the flow of a fluid—in this case, the flow of air over the wings—becomes chaotic and unstable. For more than a century, the field of fluid ...

As anyone who has experienced turbulence knows, its onset and departure are abrupt, and how long it lasts seems to be unpredictable. Fast flowing fluids are always turbulent, but at slower speeds the flow transitions to smooth ...
