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 ...

Turbulence makes many people uneasy or downright queasy. And it’s given researchers a headache, too. Mathematicians have been trying for a century or more to understand the turbulence that arises when ...

Picture a calm river. Now picture a torrent of white water. What is the difference between the two? To mathematicians and physicists it’s this: The smooth river flows in one direction, while the ...
