Illustration of daytime-warm-season boundary layer circulations and Cumulus cloud formation over complex terrain. Current research efforts in mesoscale and boundary-layer dynamics utilize novel ...

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, ...

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 ...

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 ...

I had a customer who was thermal printing strip steel. The steel is washed with solvents and blown dry. He was having a problem: When the strip's speed increased, the thermo printer would catch fire.

A body moving through a fluid experiences a drag force, which is usually divided into two components: frictional drag, and pressure drag. Frictional drag comes from friction between the fluid and the ...
