埋地油罐点火爆炸火焰发展研究

Research on flame propagation of buried oil tank

以计算流体力学软件FLACS模拟和全尺寸实体实验为基础,研究埋地油罐中汽油蒸汽被引燃时爆炸产生的火焰冲出油罐外的蔓延范围。模拟和实体实验证明,直径3m、容积为50m3的埋地油罐,以约89%的充装系数充装93号汽油,用电火花在罐内点燃,火焰的冲击高度约为10m,火焰广度约为1.5m。

Flame propagation and range on buried oil tank were researched based on FLACS and full scale test. A buried oil tank, with diameter of 3 m, cubage of 50 m3 , filled with 89% water and gasoline was ignited by an electric spark. The height of fire is about 10 m and width is about 1.5 m.
