摘要:介绍了喷射钠火试验的设计思路和如何对钠流进行散流喷射,同时描述控制系统和数据采集系统的设计和建造。通过对比实验中和程序FEUMIX计算中的蛊度和压力曲线,得到如下结论;试验中钠流主要以柱状钠火燃烧,在钠喷射过程中燃烧区空气温度上升非常迅速,并观察到最初的钠喷射高温峰值,采用FEUMIX以10%募化份额计算的空气温度与在200s时试验中燃烧区上空1500mm处空气
温度值非常一致,但压力曲线差异很大。关键调:钠;喷射;火灾

Abstract: This paper represents the design process on the test of the sodium spray fire, and how to make the liquid sodium into spraying flow, and described the construction of the trial control system and the data collecting system at the same time, During the whole test, by comparing with the temperature and pressure curve obtained by the test and computing by way of FEUMIX process, the conclusion is as follows: In the process of the experiment, the spray sodium burned mainly by way of columned sodium fire. During the sodium spray, the temperature of gas in the spray fire burning zone increased rapidly, and the higher initial peak gas temperature was observed. At the time of 200 s after sodium spray, the temperature of the gas up 1 5o0 mm aera away from the burning zone approached to the temperature computed by FEUMIX process assuming sodium at-
omized at 1o%, but the curve of pressure is very different. Key words:sodium; spray; fire
