摘要
利用球形流体力学方程和燃烧反应模型导出了无约束气云弱点火爆燃过程的压力分布场 ,编制了求解压力场的计算程序 ,可计算不同尺寸气云爆炸时各点的爆炸压力值。进行了可燃气云爆燃实验 ,对计算结果进行了考核。与实验结果相比 ,计算结果的偏差小于 2 0 %。
A numerical code is proposed to calculate the deflagration pressure fields of flammable gas cloud under weak ignition, which is deduced from combustion reaction model and gas dynamics equations in spherical coordinate. The experiments of gas cloud explosion were carried out to examine the validity of the calculations. The difference of results between experiments and calculations is less than 20%.
