Sažetak
The processes of discharge of higher density effluent into the recipient of lower density occur during
the release of wastewater into the sea from desalination process, which is increasingly common today
due to the shortage of drinking water. During such discharges, the goal is to achieve the best possible
mixing, so that the impact of water with a high salt concentration on the environment is as small as
possible. Since the jet returns to the bottom because of the influence of gravity, the use of nozzles
at an angle increases the zone in which mixing occurs. In this paper, a numerical model of effluent
discharge was made and buoyancy jets inclined at 45o were observed for different flow regimes. The
influence of density and velocity on jet characteristics is shown. The numerical model was developed
in OpenFOAM, and a comparison with experimental data from previous research is presented.
