| Zusammenfassung |
| The flow of continuously stratified fluids past obstacles was studied
analytically, numerically, and experimentally. The obstacles discussed here
include a flat strip, aligned with the flow, inclined or transverse to the
flow and a horizontal cylinder. In the flow pattern, transient and attached
(lee) internal waves, downstream wakes with submerged interfaces and
vortices, soaring singular interfaces, soaring vortices and vortex systems
are distinguished. New components of laminar flow past a horizontally towed
strip are presented. Fine transverse streaky structures on the strip in the
downstream wake were visualized. Soaring isolated interfaces, which are
internal boundary layers forming inside the downstream attached wave field
past bluff bodies were observed. With increasing of the body velocity a
vortex pair was formed directly at the leading edge of this interface. |
