The project intends to develop tools to accurate predict fountain flows. Volcanic eruptions, building ventilation and brine discharge from desalination plants are all examples of turbulent fountains and negatively buoyant jets. The project aims to conduct an investigation into the turbulent structure of fountains and negatively buoyant jets using numerical simulation and laboratory experiments, and to assess the accuracy of the commonly used integral models and test the effect of the use of more accurate entrainment relations. This may have a range of applications – enabling better prediction of environmental impacts, reduction of the adverse effects of the discharge of pollutants, and reduction in energy consumption in building ventilation and other industrial applications.

该项目旨在开发准确预测喷泉流量的工具。火山喷发、建筑物通风和海水淡化厂的盐水排放都是湍急的喷泉和负浮力喷流的例子。该项目旨在通过数值模拟和实验室实验对喷泉和负浮力射流的湍流结构进行调查，并评估常用的整体模型的准确性，并测试使用更准确的卷吸关系的效果。这可能会有一系列的应用--能够更好地预测环境影响，减少污染物排放的不利影响，以及减少建筑通风和其他工业应用中的能源消耗。
