摘要
对我国制造的首艘13.5万t豪华邮轮的IMAX影院区域,在设计局部2∶3缩尺火灾试验验证温度场可靠性的情况下,通过FDS软件,模拟研究了内部高大空间火灾发生后周围密集住舱区、狭长走廊区和电梯间前门厅的烟气蔓延、CO浓度、温度及能见度的变化.研究结果表明:烟气蔓延的速度和距离成负相关,狭长走廊烟气蔓延速度远高于住舱区的蔓延速度;楼梯口烟雾优先向上蔓延,然后再向四周蔓延;CO浓度呈现区域性、距离性分布的特点.该文分析了我国豪华邮轮影院高大空间的火灾演化规律,对邮轮安全性评估具有重要参考价值.
Aiming at the IMAX cinema zone of the first 135,000-ton luxury cruise ship manufactured in China,the reliability of the temperature field was verified by the 2∶3 scale fire test in the design part.FDS software was used to simulate the smoke spread,CO concentration and temperature changes in dense residential area,narrow corridor area and front lobby of elevator after the fire emerges in the large space inside the cruise ship.The results of the simulation study show that the speed of smoke spread is negatively correlated with the distance.The speed of smoke spread in narrow corridors is much higher than that in the cabin;the smoke at the stairway preferentially spreads upward,and then spreads around;the concentration of CO is characterized by regional and distance distribution.This analysis of the fire evolution process is of great value to the safety assessment of cruise ships.
