Analytical and Test Results for Water Mitigation of Explosion Effects
Abstract
Small-scale tests have shown that water placed in the proximity of explosives stored in a confined space can reduce the internal gas pressure and impulse from a detonation by up to 90%. In FY 97 and 98, NFESC began development of water mitigation concepts for application in confined (e.g. Missile Test Cells, Underground Magazines) and partially confined (e.g. earth-covered magazines) facilities. Tests and analyses were conducted to establish basic parametric relationships and to identify the best numerical models for prediction of effects. Numerical model results from hydrocodes and computational fluid dynamics codes are presented and compared to test data. A limited number of tests with variable confinement (amount of venting) were also conducted. Results were very encouraging, both for adequately predicting water mitigation effects and for the effectiveness of water mitigation even when venting reduces the internal gas pressure effects.
