| 摘 要： | 介绍了细水雾灭火技术在国内的主要研究进展．着重阐述了细水雾雾特性测量方法、雾发生方法及灭火有效性实验，并对细水雾的灭火机理和灭火技术未来的发展方向进行了讨论．细水雾的雾特性参数决定了它的灭火性能，目前对其测量的主要方法有LDV／APV、DPIV及扩展的DPIVS技术．传统的雾发生方法有着或多或少的缺点，因而新型的雾发生方法得到广泛地研究，如气泡雾化，所以我们对不同的雾发生方法进行了比较．此外通过一系列的小尺度和全尺度实验研究了细水雾在不同火灾场景下的灭火有效性．

| Abstract: | Some recent studies of water mist fire suppression technology in China were introduced,and the measurements of water mist characteristics,methods of generating water mist and fire suppression experiments were summarized in detail.The extinguishing mechanisms and future works of water mist were also discussed.Characteristics of water mist strongly influence fire suppression effectiveness.The LDV/APV,DPIV and advanced DPIVS systems were used to measure the spray characteristics.To varying degrees,the traditional water mist nozzles have disadvantages.Therefore,new methods of generating water mist(i.e.effervescent atomization) were investigated and different kinds of nozzles were compared.In order to study the fire suppression effectiveness in different fire scenarios,small-scale and full-scale experiments were performed. |
