| Abstract: |
| 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. |
