SIMULATION OF A DETONATION CHAMBER TEST CASE

The purpose of a detonation chamber is to ensure vapor and fragment containment during the destruction of explosive munitions. The toxic vapors generated by the detonation can be vented into a filtration unit. Compared to free air detonations, the use of a detonation chamber reduces the environmental impact of munitions destruction. The manufacture and testing of a detonation chambers is time consuming and expensive. At present, new designs are mainly based on experience with previous designs and rough estimates. A more accurate and reliable method for predicting a chambers performance would therefore be a significant aid in the design process. This paper considers the most straightforward method for predicting the performance of a chamber design, which is to simulate a munitions detonation in the chamber. The simulation is accomplished using LS- DYNA's multi-material Eulerian methods.
