A team of physicists has, for the first time, seen convincing experimental evidence for directed percolation, a phenomenon that turns up in computer models of the ways diseases spread through a ...

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 ...

Recent advances in flow dynamics and turbulence transition have significantly deepened our understanding of how laminar flows evolve into complex, chaotic turbulent regimes. While the phenomenon ...
