摘要
在综合分析烟气顶蓬射流特性的基础上,利用速度场分布不随时间变化的实验结果,计算了顶蓬射流的非稳态温度场,并与参考文献的实验结果进行了比较。其计算方法简单可行,结果合理。这一结果对火灾探测器和水喷淋器的安装设计具有一定的指导意义。
Based on the analysis the behavior the behavior of smoke ceiling jet, computation of unsteady temperature field of smoke ceiling jet is perfomed according to the experimental results that velocity distribution does not vary with time. Compared with other experimental results, the computation method is simple, and the results are reasonable. It is of importance to fire detector design and sprinkler installation.
