Abstract: Preliminary results of an experimental study carried out in a tank filled with water agitated by means of jets located at the bottom are reported in this paper. Flow visualization and PIV techniques were used to characterize the flow near the free surface. From the velocity records, the turbulent kinetic energy and velocity spectra were computed. They show the energy decay and its redistribution having place close to the free surface. Flow visualization allowed us to define a flow pattern formed by a series of quasi-periodical events near the free surface.
