摘要
对良好分层情况下的室内火灾进行建模 ,研究了实际火灾环境下的钢构件升温过程。在全尺寸的实验房间开展了油池火燃烧实验 ,通过不同的羽流模型和溢流模型 ,预测室内温度和钢构件温度的变化 ,并对羽流模型的适用性和影响计算的一些参量做了分析。
A simple model was built to describe the well stratified compartment fire, by which the temperature rise of steel element was investigated. Pool fire experiments were carried out in a full scale compartment. With different plume and spill plume correlations, the temperature development of the enclosure and steel element were modeled, then the applicability of plume models and factors affecting the calculation were analyzed. Finally, such method was put to use for design fires of a steel structured retail shop in an airport terminal building.
