Abstract
Shock tubes are routinely used across laboratories to simulate and understand blast events that are beyond a standoff distance of 5 m from an explosive charge. If we wish to simulate distances which are even closer, we find a formidable barrier in the form of shock formation distance, which is inherent to these facilities. In this work, we propose to use a (conical) shock tube having a continuously diverging cross-section to overcome this limitation. This paper puts forward the rationale behind using such a facility, some analytical relations using Chisnell’s work to characterize the conical shock tube, and some experiments that validate our assumptions.
