目的 研究舰船舱室起火后对舱室及相关邻舱温度的影响。方法 通过建立尺寸均为2.4 m×2.4 m×2.4 m的火灾发生舱室、水平相邻舱室、竖直相邻舱室3个舱室,并设计不同工况下典型油池火灾场景的火灾试验,测量3个舱室36个特征位置点的温度变化曲线,揭示舰船舱室起火对邻舱温度变化的趋势和规律。结果 通过对比水平邻舱和竖直邻舱的温度,当火源位于舱室中间时,竖直邻舱的温升快于水平邻舱,由于燃烧产生的烟气聚集在舱室顶部,舱室顶部的热传递效应更加明显,竖直舱室温升更快。当火源位置靠近水平邻舱时,水平邻舱较竖直邻舱温度上升快,但当火焰熄灭后,水平邻舱温度迅速下降,竖直邻舱由于燃烧结束后仍有大量高温烟气聚集,温度下降缓慢。结论 当舰船发生火灾导致舱室的温度不断升高时,对水平相邻舱室和竖直相邻舱室温度的影响较为显著。随着油池火源面积不断增大,火灾发生舱的温度不断增加,对相邻舱室的热传导效应更加明显,温度上升速率更快。由于燃烧产生的高温烟气大量悬浮在火灾发生舱室顶部,造成竖直相邻舱室的温度要高于水平相邻舱室。 |

The work aims to investigate impacts of ship compartment fires on temperature of adjacent compartments. Three 2.4 m×2.4 m×2.4 m compartments (fire source, horizontally adjacent, and vertically adjacent) were constructed for fire tests with various pool fire scenarios in typical operating conditions. Temperature variations at 36 characteristic positions were measured to reveal the trend and pattern of temperature changes in adjacent compartments caused by ship compartment fires. By comparing the temperatures of the horizontal and vertical adjacent compartments, it was found that when fire originated centrally, the vertical compartment experienced a faster temperature rise than the horizontal one due to ceiling smoke accumulation enhancing heat transfer. Proximity to horizontal compartments caused a faster initial temperature increase there, though post-extinction cooling occurred faster than that in smoke-filled vertical compartments. However, in the vertical adjacent compartments, there was still a large amount of high-temperature smoke accumulated after the combustion, so the temperature dropped slowly. In conclusion, when a fire occurs to a ship and causes the compartment temperature to keep rising, its impact on the temperature of the horizontally adjacent compartments and the vertically adjacent compartments is relatively significant. As the fire area in the pool keeps rising, the temperature in the fire compartment keeps rising, and the heat conduction effect on adjacent compartments becomes more obvious, with a faster rate of temperature rise. Due to the fact that a large amount of high-temperature smoke produced by combustion is suspended at the ceiling of the compartment of fire, the temperature of the vertically adjacent compartments is higher than that of the horizontally adjacent compartments. |
