Abstract:
This paper presents a computational investigation into the hydrodynamic behavior of a detonation chamber subjected to a TNT explosion, with the goal of predicting containment performance during explosive munitions destruction. Using LS-DYNA’s multi-material Eulerian approach, the simulation captures the full fluid-structure interaction—from explosive ignition to the propagation of pressure waves and their impact on the chamber walls. A detailed analysis of air-gas mixing, shock wave formation, and energy dissipation highlights the complexity of detonation hydrodynamics. By modeling parameters such as chamber geometry, explosive shape, and material behavior, the study provides valuable insight into optimizing detonation chamber design based on hydrodynamic performance.
