Considerations for Explosively Driven Conical Shock Tube Design: Computations and Experiments

Abstract

This report covers computational and experimental work related to the development and design of explosively driven conical shock tubes. The first part of the report focuses on using Lawrence Livermore National Laboratory's ALE3D shock physics code to replicate previous experimental results obtained from a 17 (full angle) shock tube. Next, a computational parameter study of various shock tube design choices, such as shock tube angle and explosive charge geometry, on the resulting air blast is detailed. Finally, experimental data using a new 10 shock tube along with some of the driver section design choices investigated in the computational parameter study is presented.
