A comparison of simulation's results with experiment on water mitigation of an explosion

This paper presents a comparison of simulation's results with the experimen tal data from a series of small-scale tests conducted by Joachim and Lunder man of the United States Army Engineer Waterways Experiment Station. The pu rpose of the experiments was to evaluate the effect of water as a mean of r educing airblast pressure from accidental explosions in underground magazin es. In the present study, a series of three-dimensional numerical calculati ons were conducted using a Multimaterial Eulerian Finite Element Code. Resu lts from the numerical simulations show good comparison with the experiment al data for the case with and without water. Our simulation ascertains the mitigation effects of water in reducing the maximum peak pressure and impul se density due to an explosion.
