Ducted surface pumps are used in reservoirs to circulate and destratify the water in order to maintain its general quality and reduce the incidence of toxic algal blooms. This project aims to improve our understanding of the circulation and mixing behaviour of the large, low velocity jets, plumes and fountains created by these pumps. Computational fluid dynamics, laboratory and field studies will be used to model and map these flow fields. The findings will have a number of potential applications including methods for improving water quality in and downstream of storages.

在水库中使用管道地面泵来循环和分层水，以保持水的总体质量，减少有毒藻华的发生。该项目旨在提高我们对这些泵产生的大型低速射流、羽流和喷泉的循环和混合行为的理解。计算流体动力学，实验室和现场研究将用于模拟和绘制这些流场。这些发现将有许多潜在的应用，包括改善水库及其下游水质的方法。
