WATER HAMMER MODELLING FOR DESALINATED WATER DELIVERY

摘要

Sydney Water's Desalination Plant has been designed to produce an annual average 250 megalitres of water per day (ML7d), and can be expanded to produce an average of 500ML/d if required. The Water Delivery Alliance (WDA), designer and constructor of the water delivery infrastructure, produced detailed water hammer models of the WDA delivery infrastructure and varying network complexities of Sydney Water's existing Potts Hill system. The performance of various software packages over a range of network complexities was investigated, with implications and opportunities in water hammer design identified. Validation of water hammer modelling with field surge testing up to 310ML7d was also undertaken, and these results and subsequent design opportunities are discussed.
