"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, ...

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 ...

Flow meters are used to measure the rate of flow of liquids or gases, just like electric meters measure the amount of electricity consumed. However, unlike electric meters, which are either ...

The flow of fluids is important in many applications ranging from blood flow in the human body to air flow over the wing of a jet aircraft. As a result, this is a required course for mechanical ...

Fluids play a crucial role in industrial processes like cooling, heating, and mixing. Traditionally, most industries would utilize Newtonian fluids—which have a constant viscosity—for such processes.

The banging of pipes often heard when a faucet is turned off or on is called “water hammer” and is due to the sudden arrest or reversal of direction of the water flow. Water hammer is a phenomenon ...

From Quanta Magazine (find original story here). Spaghetti-thin shoelaces, sturdy hawsers, silk cravats—all are routinely tied in knots. So too, physicists believe, are water, air and the liquid iron ...

Two mathematicians prove that under certain extreme conditions, the Navier-Stokes equations output nonsense. The Navier-Stokes equations capture in a few succinct terms one of the most ubiquitous ...
