In 1883, Osborne Reynolds injected ink into water in a short, clear pipe to observe its movement. His experiments showed that as the input water velocity increased, the flow went from laminar (smooth ...

Mention the word "turbulence" and you might conjure up images of bumpy flights, stormy weather, and choppy ocean or river currents. For many, turbulence is a fact of daily life, yet it is also one of ...

Trajectories in time traced out by turbulent puffs as they move along a simulated pipe and in experiments, with blue regions indicate the puff "traffic jams." The images on the left are closer to the ...

Using unconventional statistical mechanics to understand fluid dynamics, a professor helped solve a 150 year old physics problem of how turbulent fluids move through a pipe. In 1883 Osborne Reynolds ...
