Abstract
The performance of the DRES Blast Tube facility was evaluated to identify the cause(s) of apparent sub-theoretical blast tube performance and to investigate the possibility of reducing or eliminating undesired nonplanar waves in the tube. During the course of the evaluation, 38 blast tube experiments were conducted, along with a number of tests of individual blast tube components and systems. High resolution theoretical predictions of blast profiles within the tube were made using the 1D module of the Split-2D code. It was determined that the initiation energy and the ethylene rapid-injection system are both adequate, and the overall conclusion is that blast tube performance is actually quite close to theoretical, both in terms of peak pressure and pressure profile.
