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.

The stars of the "Jaws" films--sharks--have recently become the subject of a new engineering research project. The project explores energy conservation and boundary layer control in regard to a ...

Shock wave and turbulent boundary layer interactions are phenomena encountered in high-speed flows, where abrupt pressure changes associated with shock waves impinge upon the viscous layer of fluid ...

A typical challenge for re-entry vehicles during flight is an effective control of hypersonic transition and the laminar/turbulent state of the boundary layer. The state of the boundary layer is of ...

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 ...
