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 ...

"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 ...

Scientists at the University of Washington have re-created the distinctive spiral shapes of shark intestines in 3D-printed pipes in order to study the unique fluid flow inside the spirals. Their ...

From the smooth, orderly layers of laminar motion to the chaotic swirls of turbulence, understanding fluid flow is key to engineering success. The Reynolds number, continuity equation, and insights ...

Tests of a proposed friction-factor equation have shown it to be accurate for calculating pressure loss in turbulent flow for a pipeline transporting a non-Newtonian fluid, such as most crude oils and ...
