Paper Abstract

To investigate blockage phenomena and its effects on the loading of a model, in the rect-angular test section of a shock tube, for several blockage ratios, realized by simple models namely closed box-like structures, shadowgraphs were taken from the flow and wave processes, initiated by a non-decaying shock wave. Besides, pressure-time and impulse-time histories registrated at measuring points at the front, top and rear of the model are discussed. Re-sulting from these experiments recommendations can be given about the admissible blockage ratio of a simulator.
