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 ...

The boundary layer in hypersonic regimes—typically defined by free-stream Mach numbers exceeding five—exhibits a complex interplay of compressibility, high thermal gradients and non-equilibrium ...

It’s long been accepted that the smoother the surface, the lower the aerodynamic drag. That turns out not always to be the case.

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 atmospheric boundary layer (ABL) is the part of the lower troposphere that interacts directly with the earth's surface through turbulent transport processes. A coast separates two drastically ...
