摘要
本文采用区域模型对舰船火灾中烟气沿通道蔓延的热物理特征进行了计算机模拟,并根据区域模型的基本思想,采用纵向分段的方法,解决了纵向长通道内烟气蔓延中分层热物理参数不均匀问题,提高了模拟计算的准确性。模拟结果与模型实验符合较好。
A computer simulation was performed for smoke spread3long a corridor in marine fires on the basis of Zone modeling,in which the long-distence corridor was lengthwise divided into sever-al sections,the problem of lengthwise distributed nonuniformity of thermophysical parameters of smoke was resolved, and the accuracy of prediction was improved.The comparison with reduced-scale experiments has been found to be satisfactory.
