摘要
结合国内家具火灾的实际情况,通过全尺寸实验方法研究不同面料的家具自身燃烧行为及其对单室火灾动力学的影响;采用区域模拟的思想,以McCaffrey模型和通风口溢流模型对室内烟气质量守恒进行建模,研究烟气层的高度和温度;对实验结果和计算结果进行对比,分析McCaffrey模型在家具火灾情况下受限空间内的适用情况。
The full-size experiment was done to study on combustion behavior of upholstered furniture and influence of fire dynamics in single room. A simple model was built to describe the well-stratified compartment fire. Based on McCaffrey plume model and overflow model of intake, the temperature development of the enclosure and height of smoke layer were modeled. Numerical data such as temperature fields and hot/cold smoke layer height were obtained, and compared with experimental data. Then the applicability of McCaffrey plume models and factors affecting the calculation were analyzed.
