Abstract

Based on the explosion theory of point source, this study obtains the solution of a strong explosion of one-dimensional TNT point source charge, line source charge, and plate source charge blasting in a close-in flow field. Furthermore, this study investigates the propagation characteristic in the close-in field of a shock wave of the TNT spherical charge explosion in real air condition by using the dimensional state equations of real air and the detonation products of a TNT spherical charge. Based on the analysis of the examples, the study results are largely consistent with that of some existing literature. These research results provide an important reference for studying explosion mechanics and protection engineering.
