Numerical simulation of laterally confined vertical buoyant jets
In most cases, the density of wastewater effluents is less than that of the receiving water body. Therefore, the wastewater
effluents are considered buoyant jet. A typical type of buoyant jets is the outfall of the wastewater treatment plants. In order
to effectively design an outfall system, and minimize its environmental impact, the mixing mechanism of turbulent buoyant jets
must be examined. It is essential to dispose the buoyant jets in a suitable condition, because these jets have dominant negative
environmental impacts. In many cases, the effluent is bounded by limiting boundaries. This leads to a confined turbulent jet.
The mixing characteristics of confined buoyant jets can be examined in different ways including experimental, numerical and
theoretical methods. Limited studies in the literature are reported on numerical modeling of laterally confined vertical buoyant
jets. In this paper, the mixing characteristics of a laterally confined vertical buoyant jet is studies using various turbulence
models including the GGDH k-ε turbulence model which is a buoyancy-corrected model. The numerical simulation results
are compared to other models and experimental data experiments. The study demonstrates that GGDH k-ε turbulence model
improves the precision of simulations. It can thus be employed for examining the mixing characteristics of confined buoyant
jets.
