Experimental research on explosion performance of diesel fuel in the external field

  • 摘要: 通过Ø30 mm杀爆燃弹外场炮击实验,模拟车辆、装备油箱被炮火击中后二次爆炸场景,采用高速照相机、红外热成像仪分别记录引爆柴油过程和爆炸火球的温度场,对比评估普通柴油、含水型柴油和抑爆型柴油的爆炸特性。实验结果显示:炮弹射击油箱瞬间,柴油液滴被抛撒出油箱,与空气快速混合形成气溶胶,并在炸药能量作用下引发爆炸,形成爆炸火球;不同类型柴油的爆炸火球均经历3个发展阶段,但其尺寸、扩展速率和表面温度等有较大差别,普通柴油和含水型柴油的火球这3个参数比较接近,都大于抑爆型柴油;含水型柴油的油箱毁伤容积为108.00 dm3,远高于普通柴油的57.65 dm3和抑爆型柴油的38.15 dm3。研究表明,抑爆柴油中的高分子聚合物能起到较好的抑爆作用。
