Mixing of Temperature-stratified Lake Water by a Horizontal Buoyant Jet

Abstract

A turbulent buoyant jet in a stratified ambient fluid is investigated. The theoretical integral analysis approach has been used. By applying similarity hypothesis for velocity and temperature profiles and deriving an entrainment function, a general model is developed to predict jet trajectories, centerline temperature or density and velocity decay, and the dilution on the axis of a turbulent buoyant jet discharged at .arbitrary angles to stratified or uniform ambients. The effects of pressure to which density difference and curvature of the jet contribute are evaluated. Predictions obtained with the model are compared with experimental data.
