摘要

This study investigated the energy transfer characteristics of explosive-driven shock waves by detonating cylindrically shaped TNT charges within a medium-to-large-scale shock tube. Experimental results were compared against numerical simulations using hydrodynamic analysis software. The uniformity and reproducibility of reflected pressure at the tube outlet were confirmed through repeated testing. Empirical correlations were established for incident and reflected peak pressure and impulse based on explosive weight. The findings demonstrate that a shock tube system can effectively replicate high-intensity blast conditions under safe and controlled environments, offering a reliable platform for future blast impact research.
