Radial spreading of vertical buoyant jets in shallow water
… shallow water bodies. Often these effluents are buoyant with respect to the receiving environment. In many jurisdictions, regulations require that a certain dilution is achieved within a specified mixing zone. In shallow water it is likely that a portion of this dilution will have to be achieved …

An Experimental Study of Single and Multiple Turbulent Buoyant Jets in Crossflow
The phenomenon of turbulent, buoyant jets in crossflow is a fundamental fluid mechanics problem with many application areas, including jets discharged from natural and mechanical draft cooling towers. Buoyant jets have been studied for many years, and as a result there exists a large body of …

The rise and dilution of buoyant jets and their behaviour in an internal wave field
A new buoyant jet model is presented in this thesis to simulate the trajectory and dilution of a fluid from a single port or line source. The new features include: A generalised derivation of the governing equations so that buoyant jets discharged from a source of any shape can be modelled within …

Entrainment Characteristics of Turbulent Round Gas Jets Submerged in Water
The entrainment process in two-phase buoyant jets differs significantly from their singlephase counterparts, and is not well understood. Entrainment models developed for singlephase flow are often used in two-phase jetting simulations, albeit with limited success. In this work, Particle Image …

Heat transfer in stratified flow.
… model proposed by Koh and Fan for surface buoyant jets. Under steady state conditions the flow consists of a surface layer entraining fluid from below and losing heat at the surface. This layer subsides at the downstream boundary of the pond and passes through the pond outlet. A …

Analysis and Modelling of Desalination Brines
… into the sea is an inclined negatively buoyant jet of a single port or multi-diffuser. Two small-scale experimental studies were conducted to investigate the behaviour of a dense jet discharged into lighter ambient water. The first lab-scale experiment concerned the benefit of the …

A Comprehensive Study of Buoyant Rosette Jets Using Laboratory Experiments, CFD, and Machine Learning
… the complex mixing behavior of the resulting buoyant jets poses a challenge for accurate modeling, requiring more advanced mixing methods. This study integrates laboratory laser-induced fluorescence (LIF) experiments, computational fluid dynamics (CFD) simulations, and machine learning (ML) …

Fluid flow and sound generation at hydrothermal vent fields
… data. Theoretical examination of hot, turbulent, buoyant jets exiting from hydrothermal chimneys revealed acoustic source mechanisms capable of producing sound at levels higher than ambient ocean noise. Pressure levels and frequency generated by hydrothermal jets are dependent on chimney …
