大型船舶火灾预警应急通道通风度数值模拟研究

Numerical simulation of ventilation degree of emergency passage for large ship fire warning

为保障船舶航行安全,对大型船舶火灾预警应急通道通风度数值进行模拟研究。为保障模拟结果的准确性,结合质量守恒、动量守恒定律和能量守恒定律等相关原理,对船舶火灾预警应急通道排烟情况进行建模,观察分析通道内部火灾烟雾气体循环和排放情况,根据烟雾产生和循环情况计算船舶应急通道的通风度数值。通过对比标准参数进行实验检测,检测结果证实,对应急通道通风度数值的模拟充分满足研究要求。

In order to ensure the safety of ship navigation,the numerical simulation of ventilation in emergency passage of large-scale ship fire warning was conducted.In order to ensure the accuracy of simulation results,combined with the relevant principles of mass conservation,momentum conservation law,energy conservation law and so on,the smoke exhaust situation in the emergency channel of ship fire early warning was modeled,the gas circulation and emission of fire smoke in the channel were observed and analyzed,and the ventilation value of the emergency channel of ship was calculated according to the smoke generation and circulation.By comparing the standard parameters for experimental testing,the test results confirmed that the simulation of emergency channel ventilation fully meets the research requirements.
