摘　　要：地下储油库是典型的受限空间结构。一旦发生油气爆炸燃烧,爆炸压力波和火焰的传播将受到众多因素的影响。通过数值模拟的方法研究了在地下油料洞库中油气混合物由弱点火引起爆炸燃烧的发展过程,以及爆炸压力波和火焰经局部扰动后的变化过程,并将数值模拟结果与实验结果进行了对比和综合分析,得到了地下油库油气爆炸过程的基本参数,揭示了爆炸过程中油气浓度、湍流对燃烧与压力波发展影响的规律。研究结果对地下受限空间油气爆炸过程的进一步研究以及爆炸灾害的预防都具有参考价值。Underground fuel depots are the structures with complicated confined space. Once combustible gas is ignited, it may lead to explosion, the explosion pressure wave and propagation of flame will be influenced by many factors. The results of numerical simulation on fuel-air mixture explosion triggered by weak ignition in underground oil depot are shown in this paper. The numerical simulation results were basically in agreement with the experimental results, and the effect of mixture compositions, boundary conditions, turbulence on combustion and pressure waves was revealed.
