Experimental and numerical study of sprinklers for improved fire safety

喷水灭火装置是一种常用的灭火方法。目前对喷头缺乏详细的知识可能会导致设计保守和成本过高，往往限制了这些经过验证的救生设备的安装。在这个项目中，奥雅纳私人有限公司和新南威尔士州消防队参与了使用定制设计的试验台、基于激光的测量和数值模型来检查喷头的行为。这将提高对喷水灭火装置规格和安装的信心，该项目将在澳大利亚以外的地区使用和具有重要意义。成功的执行承诺减少生命和财产的损失，并节省资金。

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.
