This study analyzes the propagation and reflections of regular Mach and shock waves through small-scale experiments and numerical modeling of an explosion in a gas storage plan. The gas storage area is a "U-shape" and contains two racks of 9 horizontal bottles (3 x 3) each. An explosive charge is located in a corner at the closed end of the system. The analyses of the shock waves and the effects of overpressure are conducted both inside and outside the plant. (C) 2013 Elsevier Ltd. All rights reserved.
