Abstract
This paper visualizes explosions in a subsurface magazine model constructed underground to mitigate the effects of blast waves. Numerical simulations discuss the effect of water that is put inside the magazine model. The simulation data shows that the peak overpressures on the ground agree with those in the previous experiment. The increases of kinetic and internal energies of water are then estimated, and that the heat transfer at the interface of water and air is a dominant factor to mitigate the blast wave on the ground.
