摘　　要：为了研究网络火灾中风流流动特性,搭建了一个网络火灾模拟小尺寸实验台。该实验台包括1条着火支路和2条旁侧支路。根据旁侧支路长度和初始风速的不同组合方式,开展了7种工况下的模拟实验。采用热线风速仪结合示踪技术观测旁侧支路的风流逆转过程。结果表明,由非稳态分析法得到的判定准则是合理的。In order to study airflow characteristics of network fire,a network fire simulation and small size experimental table were built.This table consisted of one fire branch and two lateral branches. According to different combination modes of lateral branch length and the initial wind speed,seven simulation tests were carried out. The airflow reversal of lateral branch was monitored with hot- wire anemometers and tracer technology. The results showed that the criterion obtained by non- steady- state analysis method was reasonable.
