摘要
从流体力学和化学反应动力学方程出发 ,建立了描述密闭空间内局部可燃气云爆炸过程的数学模型。应用SIMPLE算法进行求解 ,得到了密闭空间内局部可燃气云一维爆炸场的发展过程 ,计算结果符合物理现象和规律 ,说明该数学模型和数值算法较为合理 ,计算结论对工程设计有参考价值。
Based on fluid mechanics and chemical reaction dynamics equations, a mathematical model was built and solved with SIMPLE algorithm. The development course of single one-dimension explosion field of local combustible gas cloud in enclosed space was obtained by lots of computed data. Computed results were essentially in accord with the phenomenon and regulation of gas explosion in enclosed space. Therefore, the mathematical model and the numerical algebra were reasonable and some results can be used in project design as reference.
