An experimental investigation was conducted to compare the blast mitigation performances of water layers, whose mass ratios to an explosive were \( m_{{\text{W}}} /m_{{\text{E}}} = 12.2,44.5,\;{\text{and}}\;107.2 \), with water droplets surrounding the explosive. The blast waveforms were measured using pressure transducers, and the motion of the water layer was recorded using a high-speed camera. When m_W/m_E was equivalent between the water layer and water droplets, the water layer exhibited less mitigation of the peak overpressure and positive impulse than the water droplets. The results demonstrated high efficiency of the water droplets in blast mitigation and the existence of an optimal apparent density of the water barrier. The velocities of the water layers determined using high-speed photography agreed with the prediction model of the barrier material accelerated by explosion. It suggested that the primary cause of the blast overpressure mitigation by the water layer was the allocation of the explosion energy into the kinetic energy of the water.

进行了一项实验研究，比较了水层与炸药的质量比为\（m _ {{\ text {W}}} / m _ {{\ text {E}}} = 12.2,44.5， \; {\ text {and}} \; 107.2 \），炸药周围有水滴。使用压力传感器测量爆炸波形，并使用高速相机记录水层的运动。当m _W / m _E当在水层和水滴之间相等时，与水滴相比，水层对峰值超压和正脉冲的缓解较小。结果表明，在缓解爆炸的过程中，水滴具有很高的效率，并且阻水层具有最佳的表观密度。使用高速摄影法确定的水层速度与爆炸加速的阻隔材料的预测模型一致。这表明水层缓解爆炸超压的主要原因是爆炸能量分配到水的动能中。
