Abstract
The effects of detonations of different charge weight in a munition storage are investigated. The expansion of shock waves in the experimental tunnel system at Reiteralpe/Germany and generated shock patterns are shown in detail. Interest is focussed on transmission of energy through the tunnel system to an adjacent munition store. Development and distribution of pressure, temperature and energy in this storage are investigated. Special regions of interest are close to the main tunnel's end and exit with bifurcation to adjacent storage. Time histories of overpressure, stagnation pressure, temperature and Mach number are computed at stations distributed inside the tunnel system and coinciding partially with experimental stations. A detailed comparison with experimental results is done. Good agreement between computations and experiments is found.
