Paper Abstract

Indoor detonations in buildings with several linked rooms present an important and complex problem. Experimental studies in small-scale models using Nitropenta charges of 0.5-g have been performed to obtain a database for indoor detonations in a multi-chamber system. Floor and ceiling of the model consist of a transparent material. This made it possible to visualize the flow field inside the structure. Pressure gages were installed in all rooms. The paper discusses the influence of the charge position as well as effects of venting holes in the detonation chamber. It also focuses on characteristics of the energy release and the related pressure effects if the system contains an inflammable material and the detonation provides mixing with air and initiates combustion.
