Abstract: For the purpose of efficiently designing an outfall system and accurately assessing the environmental impacts of the system, it is necessary to investigate the mixing processes of a turbulent buoyant jet. When a turbulent buoyant jet is dynamically bounded by boundaries, it can be called a confined turbulent buoyant jet. In the present paper, the mixing properties of a laterally confined vertical buoyant jet is simulated using the GGDH k-? turbulence model and the results are compared to other models, available and present experiments. The results show that the buoyancy-corrected model can improve the accuracy and can be used for investigating the mixing properties of a laterally confined vertical buoyant jet
