A Comparison of Simulation’s Results with Experiment on Water Mitigation of an Explosion

Abstract

This paper presents a comparison of simulation’s results with the experimental data from a series of small-scale tests conducted by Joachim and Lunderman of the United States Army Engineer Waterways Experiment Station. The purpose of the experiments was to evaluate the effect of water as a mean of reducing airblast pressure from accidental explosions in underground magazines. In the present study, a series of three-dimensional numerical calculations were conducted using a Multimaterial Eulerian Finite Element Code. Results from the numerical simulations show good comparison with the experimental data for the case with and without water. Our simulation ascertains the mitigation effects of water in reducing the maximum peak pressure and impulse density due to an explosion.

Numerical simulation of a novel blast wave mitigation device

“…The results showed that water medium delays the shock front and reduces the magnitude of initial peak shock pressure by 40%. Chong et al [10] numerically simulated the blast mitigation process by water using a threedimensional model. Results from their numerical simulations showed good agreement with experimental data for cases with and without water.…”

Experimental study of water tank under impulsive loading

“…Water effects on blast wave mitigation have been studied by experimental and numerical methods for decades [2][3][4][5][6][7][8]. Both experimental and numerical results showed that water a r c h i v e s o f c i v i l a n d m e c h a n i c a l e n g i n e e r i n g x x x ( 2 0 1 4 ) x x x -x x x a r t i c l e i n f o The performance of stainless steel water tank subjected to impulsive loading was experimentally studied in this paper.…”

Experimental Investigation of a Novel Blast Wave Mitigation Device

“…The results showed that water medium delays the shock front and reduces the magnitude of initial peak shock pressure by 40%. Chong et al [2] numerically simulated the blast mitigation process by water using a three-dimensional model. The peak pressures on the target with and without water have been obtained and analyzed.…”
