项目标书摘要：对地下组合受限空间火灾分区现象进行深入，系统(六种结构、大范围尺度变化，不同工质与边界条件等)模拟实验(包括可视化)和机理研究以及理论分析；建立火灾分区较系统的应用基础理论体系(包括相似准则，临界判据，有关特征参数计算关系式等)。探讨地下建筑火灾消防新技术原理。对发展地下建筑消防技术与提高消防设计水平具有重要意义。
Application Abstract: The studies have been carried out according to the research plan and the important development and conclusions are obtained.The research work includes the visualization and the control mode of fire,the flame behavior,the key phenomenon,the zoned phenomenon of the fire(including the zoned phenomenon occurring and the forming),the developing process and laws(including the temperature,ingredients,and the velocity of flow in different zones,the spread of the flame zone and the spread of the fire,et al),initial modes,the measurement of the smoke layer and zones,critical combustible distance and the study of two-dimensional and three-dimensional model of fire and the computer simulation basing on the zoning theory.The important progresses has been obtained especially in the occurring and the forming of the zoned phenomenon in fire,the spread of the flame zone and the spread of the fire,combusting velocity of the combustion zone,the relationship between the size of underground confined spaces and the fire,the relationship between different combustable mediums and zoned phenomenon,three-dimension numerical simulation based on large eddy model and et al.Sixteen papers have been published and 8 persons got or will get their Ph.Doctor degrees and Master degrees through the studies.Great effects of the experimental results and theories have been had through the forms of papers,conferences and lectures and et al.
