Abstract

In this work experimental data on the geometry of dense inclined jets issuing in a lab-scale glass rectangular tank are presented. The surrounding fluid was always tap water at room temperature while the dense jets were water solutions of NaCl. Four parameters were changed in the experiments, namely nozzle diameter and inclination, and jet density and flow rate. Jet trajectories were revealed by a colored tracer. Images of the jet were recorded by a digital camera and then further digitally processed, eventually resulting in a time-averaged tracer intensity field. All the jet geometrical parameters, once normalized, were found to be very well correlated to the Densimetric Froude number. Moderate jet viscosity variations were found non to significantly affect jet behavior. The reported data allow a quick and easy estimation of maximum rise level, position of the trajectory maximum and impact point distance of dense jets issued at different angles above the horizontal.
