Openings' Shape and Location Effects on the Pressure Field in a Partially Confined Explosion

Abstract:

The paper presents a study aiming at understanding the effect of the shape, location and number of openings on the pressure characteristics due to a partially confined explosion inside a cubicle room. The study summarizes a series of numerical analyses that were performed on a room with rigid walls having a limited venting openings area. The analysis was carried out with a commercial program AUTODYN11, using the Eulerian multi-material approach.
