以交换器入口端和蒸发器出口端的管道为例,研究管道中液态钠泄漏所产生喷射钠火的成因和影响后果,研究实际泄漏情况下钠的泄漏流速和形成钠滴的大小,比较模拟水喷射下的水流速和水滴大小,理解液滴在不同流量下和不同大小喷嘴的喷射形式和相互关系,选择合适的钠喷射喷嘴开展钠喷射实验,获得喷射钠火的相关数据,帮助理解钠喷射燃烧现象.%Spray fire due to the leakage of sodium from pipe of heat exchanger nearby was analyzed to understand its cause and results. The rate of sodium leakage and the diameter of sodium droplet were developed in the piping under postulated fire scenarios. Comparing to the rate of flow and droplet diameter with water spray experiments, on the basis of the analysis of the formation for droplet spray and parameters relationships with different sizes of the hole and flow rate? Sodium spray nozzle is selected to gather data of spray fires that will result in more advanced understanding of sodium spray combustion phenomena.
