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 ...

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 ...

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 ...

Researchers from the University of Washington want to improve the pipe. Specifically, they are developing a flexible pipe with an interior helical structure that makes fluid flow one way and not the ...
