符号数学运作双层区域火灾模型

摘要

本文运用符号数学MATLAB及MAPLE V计算双层区域模型ASET的方程式,考虑两条基本方程,报告由六所面积10至100平方米的房间,在2个设计火灾下共十二个模式例题的环境及结果也和ASET及FIREWIND程序比较.%The equations on the two-layer fire zone model ASET for a chamber with air supplied through leakage are solved by the symbolic mathematics programme MATLAB and MAPLE V. Two key equations are considered.A total number of 12 simulations were carried out on two design fires in six compartments with floor area varying from 10 to 100 m2. The results are compared with those simulated by ASET itself and another software FIREWIND.
