有限长度倾斜通道内火灾近上壁面区域温度特性
Temperature characteristics nera the ec iling of an inclined channel with finite length in case of fire
摘要
Abstract
In order to explore the motion characteristics of hot smoke, a laboratory bench of a short inclined rectan-gular channel was constructed to conduct fire experiments.Methanol, ethanol and propanol were taken as fuel with the channel angles of inclination being 0°, 3°, 6°and 9°, respectively.The temperature distribution in the region near the ceiling was measured and the corresponding variation law between dimensionless temperature and dimen-sionless length was ascertained.Experimental results showed that the inclination change can be obtained utilizing the temperature variation formula of horizontal channel and the variation formulas of the temperature decaying coeffi-cient in the regions of upstream and downstream.关键词
