Abstract

Measurements of the time of arrival of shock waves from explosions can serve as powerful markers of the evolution of the shock front for determining crucial parameters driving the blast. Using standard theoretical tools and a simple ansatz for solving the hydrodynamics equations, a general expression for the Mach number of the shock front is derived. Dimensionless coordinates are introduced allowing a straightforward visualization and direct comparison of blast waves produced by a variety of explosions, including chemical, nuclear, and laser-induced plasmas. The results are validated by determining the yield of a wide range of explosions, using data from gram-size charges to thermonuclear tests.

冲击波运动学:理论、实验与应用

对爆炸产生的冲击波到达时间的测量可以作为激波锋面演变的有力标志，用于确定驱动爆炸的关键参数。利用标准的理论工具和求解流体动力学方程的简单方法，导出了激波前缘马赫数的一般表达式。引入了无因次坐标，可以直接可视化和直接比较各种爆炸产生的冲击波，包括化学爆炸、核爆炸和激光等离子体爆炸。通过使用从克大小的装药到热核试验的数据，确定大范围爆炸的当量，验证了这些结果。

期刊介绍： Shock Waves provides a forum for presenting and discussing new results in all fields where shock and detonation phenomena play a role. The journal addresses physicists, engineers and applied mathematicians working on theoretical, experimental or numerical issues, including diagnostics and flow visualization. The research fields considered include, but are not limited to, aero- and gas dynamics, acoustics, physical chemistry, condensed matter and plasmas, with applications encompassing materials sciences, space sciences, geosciences, life sciences and medicine. Of particular interest are contributions which provide insights into fundamental aspects of the techniques that are relevant to more than one specific research community. The journal publishes scholarly research papers, invited review articles and short notes, as well as comments on papers already published in this journal. Occasionally concise meeting reports of interest to the Shock Waves community are published.
