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 ...

Researchers have discovered a mathematical formula that may enable more precise models of turbulence, with practical implications in areas as diverse as weather forecasting, pollutant control, engine ...

A sneeze. Ocean currents. Smoke. What do these have in common? They're instances of turbulence: unpredictable, chaotic, uneven fluid flows of fluctuating velocity and pressure. Though ubiquitous in ...

Since at least the 1920s, scientists have been puzzled by the turbulence that arises when a liquid hits a wall. For instance, what happens when water violently sloshes against the side of a pool or ...

One of the first things most people do in the morning is turn on a tap in the bathroom. Provided we are not too sleepy, we cannot fail to notice what is often considered to be the greatest unsolved ...

This section was adapted from The Engine and the Atmosphere: An Introduction to Engineering by Z. Warhaft, Cambridge University Press, 1997. How many times a day do we turn on a faucet? Do it now.

To most people, turbulence is the jolt felt by jet passengers moving through a rough pocket of air. But to scientists, turbulence is the chaotic flow of a gas or liquid, in which parts of the current ...
