Entrainment and mixing in turbulent negatively buoyant jets and fountains

Indicative Funding
$75,000 over 3 years (administered by The University of Sydney)
Summary
Volcanic eruptions, building ventilation and brine discharge from desalination plants are all examples of the occurrence of turbulent fountains and negatively buoyant jets. Management and design of these processes requires the ability to accurately predict these flows and, in particular, entrainment and mixing with the ambient fluid. We will conduct the first detailed investigation into the turbulent structure of fountains and negatively buoyant jets using numerical simulation and laboratory experiments, assess the accuracy of the commonly used integral models and test the effect of the use of more accurate entrainment relations.

Thermal stratification, overturning and mixing in riverine environments

Indicative Funding
$83,775 over 3 years (administered by University of Sydney)
Summary
Thermal stratification is common in Australia's rivers due to our hot, drought-prone climate and high human demands relative to available supply, which has led to a significant reduction in flows relative to natural levels. Thermal stratification inhibits mixing, creating stagnant conditions characterised by low oxygen levels and increased concentrations of contaminants, leading to algal blooms, fish kills and systemic damage to ecosystems. The aim of this project is to develop predictive models for the effects of physical processes such as night-time cooling, wind, turbulence and currents n riverine thermal stratification. This will enable a more accurate determination of the flow rates required to maintain the health of our river systems.
