横長開口から噴出する熱気流の鉛直壁面近傍温度分布

摘要

The focus of this research was placed on the shape of the plumes of hot air under various flammable material conditions for openings with a horizontal shape. A series of experiments using a full-size compartment focusing on the shape of the temperature distribution in order to obtain knowledge related to the shape of the temperature distribution were conducted. The following was found from the experimental results.: a)Temperature attenuated with height Z above the opening to essentially the-1 power, b) The temperature distribution near the wall above the opening exhibited a correlation with the temperature distribution of the rectangular heat source in free space, c) Under the conditions where ethanol and heptane were used,Q_(ef.crit)and Q_(ef.e) tended to match well.%本研究では、横長開口から噴出する熟気流の温度分布性状について、実大規模の区画を使用した実験を実施し、区画内の可燃物が異なる場合の温度分布性状への影響を考慮した定量的な知見の収集を行い、更に、横長開口から噴出する熟気流の鉛直壁面近傍温度分布の簡便な算定モデルを提案した。
