Oscillating jet flow

  • Oscillating jet flow

The experiment was carried out at the Hydraulics laboratory of RomaTre University. The temporal evolution of an oscillating jet flow developing downstream of a drop structure is shown. The oscillating jet is a transition flow condition between a surface wave jet flow (undular jump) and a submerged jet flow (hydraulic jump). In Figure a) a surface wave jet is shown: a main downstream flow is positioned close to the water surface, while close to the bottom an upstream flow moves the sand on the apron. In Figure b) and c) the surface wave jet changes into a submerged jet with a downstream flow close to the bottom, which moves the sand downstream, and an upstream flow close to the water surface. In figure d) the submerged jet is changed again into a surface wave jet.

This web site was launched by Prof. Michele Mossa of the Polytechnic University of Bari (Italy) with the initial support of Fondazione Caripuglia, Bari, Italy for the Research Project LIC-MON of 2003 and of the Project IMCA (Integrated Monitoring of Coastal Areas) financed by MIUR PON D.M. 593/00. Later, the initiative was supported with other Prof. Michele Mossa’s funds, most recently provided by the RITMARE Project.
