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.

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 ...

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 ...
