| 摘 要： | 采用FDS对舰船动力机舱进行火灾模拟。分不同热释放速率、进风口位置及火源位置设5种情况模拟,分析对机舱舱壁温度分布的影响规律。火源正上方顶部温度升高迅速,应注意结构强度。进风口设置在下部易于为火源提供氧气,不建议采用。进风口设置在顶部时高温烟气不易聚集,有助于降低壁面温度。

| Abstract: | Fire in engine room of ship was simulated by FDS.5 scenes with different Heat Release Rate,air inlet and position of fire origin were simulated to analysis it's effect to temperature diffusion.The structure strength on top of fire should be paid more attention since the temperature there raised fast.Low air inlet was not suggested because it may bring more oxygen to fire.High air inlet makes the high temperature smoke not easy to assemble on top of fire and is helpful to decrease the temperature of wall. |

| Keywords: | engine room fire simulation temperature distribution air inlet smoke vent |
