本文研究了方形直管内的爆炸，以了解水对外部爆炸波的缓解作用。数值模拟被用来评估的效果，是把管内的水。水的存在降低了外部超压峰值，这与实验数据吻合较好。水的动能和内能的增加进行估计，并在空气/水界面的内部能量转移被证明是一个重要的因素，在本数值方法中，在减轻爆炸波。
This paper investigates explosions in a straight square tube in order to understand the mitigation effect of water on blast waves that emerge outside. Numerical simulations are used to assess the effect of water that is put inside the tube. The water reduces the peak overpressure outside, which agrees well with the experimental data. The increases in the kinetic and internal energies of the water are estimated, and the internal energy transfer at the air/water interface is shown to be an important factor in mitigating the blast wave in the present numerical method.
