Abstract: Experimental results obtained in a jet agitated tank are presented in this paper. A tank filled with water is agitated by means of jets located in the bottom. Velocity measurements and flow visualization experiments allowed us to identify a secondary motion scaling with the flow depth, forming well defined cells along the tank diagonals. Turbulence intensity measurements show presence of an homogeneous and isotropic turbulence region, where the kinetic energy decays as the inverse of the square of the distance from the bottom. Relationships to define the location where the homogeneous and isotropic region starts are also found.
