Abstract:

Investigations were made of the partition of mechanical and non- mechanical energies resulting from the detonation of a water-cased explosive surrounded by air in a closed piston-fitted vessel. Of eight postulated governing parameters, the three more important parameters are given, i. e., charge weight, mass-per-frontal area, and water-to-air ratio, on energy partition. Ana lytic equations were established that express energy partition in terms of model-plug response to simulated excursion-type loading. These equations require for their solutions only a knowledge of the displacement-time history of the model plug. Eleven energy-partition experiments were conducted in a test apparatus that simulates the Enrico Fermi Atomic Power Plant. Experimental displacement-time data were graphically and analytically treated to obtain various plug-response functions and the subject energy partition. For the subject experiments only, it is concluded that increasing water-to-air ratios have a marked decreasing effect on energy partition ratio of mechanical to non-mechanical energy, that increasing mass-per-frontal-area ratios have only a slight decreasing effect on energy partition, and that increasing charge weights have a slight increasing effect on energy partition.
