摘要

Water film flows are an effective means of inhibiting the spread of fire To investigate the effectiveness of water film flows the unknown heat transfer characteristics must be known on both surfaces of the fireproof material However due to the extreme heat measuring the temperature on the hot surface is problematic Consequently in the present study the unknown surface heat flux surface temperature and overall heat-transfer coefficient are computed using a hybrid inverse heat conduction scheme comprising the Laplace transform and finite difference methods with a sequential-in-time concept and the least squares method based on the experimental temperature measurements obtained on the cold surface The proposed method is applied to investigate the heat transfer characteristics of three different materials with and without a water film flow namely a glass pane a steel roller door and a curtain Generally the results show that for each material the use of a water film flow yields a significant improvement in the heat resistance on both the hot and cold surfaces due to an enhanced latent and sensible heat transfer Specifically the water film lowers the average surface temperature due to the effects of water evaporation
