Experimental and numerical study of sprinklers for improved fire safety

点击翻译按钮获取中文摘要

Fire sprinklers are a common method for extinguishing fires. Current lack of detailed knowledge about sprinklers can lead to conservative design and excessive cost, often limiting the installation of these proven life-saving devices. This project sees the involvement of Arup Pty Ltd and the NSW Fire Brigade in examining the behaviour of sprinklers using a custom-designed test-rig, laser based measurement and a numerical model. This will result in improved confidence in sprinkler specification and installation and the project will have use and significance beyond Australia. Successful implementation promises reductions in the loss of life and property as well as financial savings.
