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 ...

The study of hypersonic boundary layer transition and instability encompasses the complex processes by which a thin, near-wall flow region shifts from a smooth, laminar state to a highly chaotic, ...

In an experiment on how turbulent boundary layers respond to acceleration in the flow around them, aerospace engineers at the observed an unexpected internal boundary layer. In an experiment on how ...
