Propagation of a jet of viscous liquid in a medium containing a density jump

The results of an experimental investigation into the laws governing the propagation of a jet of viscous liquid in a medium incorporating a density jump are studied for a Reynolds number range of 25 ≤ R ≤ 20·103. In addition to jets normal to the jump surface (vertical jets), horizontal jets travelling along the interface between the heavy and light liquids (jump surface) are examined. Photographs are presented, together with dynamic pressure measurements, illustrating properties of the jets studied which are unusual for a uniform medium: the extinction of turbulence, the existence of a limiting jet length, anisotropy of the jet, etc. An approximate explanation (within the framework of boundary-layer theory) is given for the effects in question.
