本文报道了一对圆柱形爆炸波在空气中相互作用的实验和计算结果。波是由爆炸的电线产生的，观察到对称和不对称的相互作用。实验数据包括波相互作用的纹影照片、它们的半径、激波马赫数和压力与时间的关系，以及激波规则/不规则相互作用过渡条件的各种交会图和数据。流场计算的帮助下，“总变差递减”（TVD）的方法，并出现合理地代表实验结果。对Sakurai（1965）和Oshima（1960）所讨论的爆炸尺度律也给予了一些注意。
This paper reports the results of experiments and computations on the interaction of a pair of cylindrical blast waves in air. The waves were generated by exploding wires, and both symmetrical and unsymmetrical interactions were observed. The experimental data includes schlieren photographs of the wave interactions, their radii, shock Mach number and pressure versus time, as well as various cross plots and data on the shock regular/irregular interaction transition condition. The flow fields were computed with the help of the “Total Variation Diminishing” (TVD) method, and appear to represent the experimental results reasonably well. Some attention is also given to the blast scaling laws of the type discussed by Sakurai (1965) and Oshima (1960).
