摘要
综述了大空间建筑火灾烟层界面高度的判定方法。给出了烟层界面的定义。基于烟气特性参数将烟层界面的判定方法分为温度判定法、能见度判定法和燃烧产物浓度判定法。分析并比较了针对实验数据和场模拟数据的各种数据处理方法。
Reviews the determination methods of the smoke interface height of large space building fires. Presents the definition of smoke interface. Classifies the determination methods into those by temperature profiles, visibility profiles and combustion product concentration profiles in terms of characteristic parameters of smoke. Analyses and compares different data processing methods for experimental and numerical results.
