Turbulence is one of the great mysteries of modern science. It is also one of the most important, as most of the flows we're interested in are turbulent. In some applications, such as industrial ...

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 ...

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 ...
