The onset of turbulence in pipe flow has defied detailed understanding ever since the first observations of the spatially heterogeneous nature of the transition. Recent theoretical studies and ...

"The pipe-flow problem has always been one of the most basic and important in the study of fluid mechanics, and in many ways the field was developed to address this problem," explains Ristroph, ...

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 ...

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 ...

If you're buying an old house, beware of old galvanized steel water pipes. These pipes build up with sediment on the inside, making the inside diameter of the pipe smaller and smaller over time, ...
