Figure 1: Predator–prey oscillations in transitional turbulent pipe flow at nominal Re = 2,600, for a pipe of radius R = D/2. These numerical results suggest that the large-scale zonal flow and the ...

Modern civilization depends on the transport of liquid and gases in systems of pipes, just as humans depend on the transport of blood through arteries and veins 1. As fluids move through pipes, they ...

Until now it had been assumed that, once a flow of a fluid has become turbulent, turbulence would persist. Researchers have now shown that this is not the case. In their experiments they managed to ...

Researchers have discovered a new way to help liquid flow in only one direction, but without using the flaps that engines and our circulatory system rely upon to prevent fluid backup. The team created ...
