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 planetary boundary layer (PBL) is also known as the atmospheric boundary layer (ABL). It is the lowest part of the atmosphere and its behavior is directly influenced by its contact with the ground ...

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, ...

A group of University of Arizona engineering faculty members is working together to advance research into vehicles moving five times faster than the speed of sound. Over the course of 2020, faculty ...

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.

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 ...
