Quantification of Mechanisms for Blast Mitigation with Water-Filled Containers

HUON BORNSTEIN, SHANNON RYAN, ADRIAN P. MOURITZ

Abstract


Validated numerical simulations were used to investigate the physical mechanisms responsible for the blast mitigation provided to steel plates by water-filled containers in the near-field. The flying ring technique was used to define the spatial distribution of loading on the target, in order to isolate and quantify the importance of each mechanism. Increasing the height of the water-filled container was found to increase the loading at the top surface of the container. To offset this additional loading, the roles of the shadowing, mass and spreading mitigation mechanisms were enhanced as the height of the container increased. This resulted in the taller containers providing superior blast mitigation. The trade-offs between the loading and mitigation mechanisms were shown to result in an optimized container radius.
