Fluid-Dynamics of Explosions in Multi-Chamber Systems Phenomenology Test Program

Abstract

The report focuses on the topic of indoor detonations in multi-chamber structures. The central part of the presented project investigated a generic model of a single-story building. By means of PETN-charges in the range of 0.5g model scales of about 1:70 were feasible. Main diagnostic were pressure measurements at the model walls and high-speed visualization of the flow field. The tests are well reproducible and easily repeated; thus a number of parametric changes was feasible (e.g., variation of the charge location, size of a venting hole in the chamber, where the detonation occurs). In addition, experiments on selected typical components of a multi-chamber structure (e.g., corridors, connecting doors, staircases) were also performed in a shock tube, in order to investigate the typical flow field phenomena in dependence from the Mach number.
