Abstract
The work presented in this paper investigates the use of a shock tube designed to propagate a shock wave through the air (commonly denoted as “air blast”) resulting from the detonation of an explosive charge. This explosively driven shock tube has a conical geometry, which allows for the use of relatively small charges to approximate the Friedlander waveform due to the free-field detonation of much more massive explosive charges. Both previous experimental data and new computational work are presented to illustrate the influence of various design parameters of the shock tube’s explosive charge and driver section—the portion of the tube that confines the explosive charge and transitions to the main tube section confining the flow—on the resulting air blast.
