摘　　要：利用FDS对标准燃烧体及三层货架仓库进行真实物品的仿真建模,探究了不同流量K系数分别为202、161、115下,以及不同喷水压力0.4MPa、0.3MPa、0.2MPa及临界喷水强度16.3 L/(min·m^2)下的ESFR喷头灭火效果。模拟结果表明当喷水强度小于16.3L/(min·m^2)便不能实现抑火而喷水强度取值27.1~36.1L/(min·m^2)是合理的,同时提出了合理工程设计参数。Using FDS to simulate the real objects of the standard combustion body and the three-story warehouse,explore ESFR sprinkler effect in different flow K-factors of 202,161,115,and different spray pressures of 0.4MPa,0.3MPa,0.2MPa and critical water spray intensity under 16.3L/(min·m^2).The results show that when the water spray intensity is less than 16.3L/(min·m^2),it cannot achieve fire suppression and the water spray intensity value of 27.1~36.1L/(min·m^2)is reasonable,and finally proposed reasonable engineering design parameters.
