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 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, ...

The transfer of oxygen, carbon dioxide, and ammonia across fish gills is waterflow-dependent, oxygen being the most flow sensitive and ammonia the least, in the reverse order of their solubilities.

If there are no shear stresses present, there is no fluid deformation, and the behavior of a fluid is described by the bulk modulus relating the pressure and the compression strain. In the presence of ...

Physicists have shown how liquids on solid surfaces can be made to slide over the surface a bit like a bobsleigh on ice. The key is to apply a coating at the boundary between the liquid and the ...
