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 ...

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 ...

Why is Christian Science in our name? Our name is about honesty. The Monitor is owned by The First Church of Christ, Scientist, and we’ve always been transparent about that. The church publishes the ...

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 ...
