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.
