Modeling of High Explosive Blast Inside a Destructible Relaxation Structure

Numerical simulation of HE blast wave interaction with a water-filled container used as a destructible protective device with a combined method of suppressing the damaging blast effect was obtained. Shock-wave systems and processes that occur during the detonation of a condensed substance (high explosive, HE) in blast-protective enclosures bunkers were simulated, including the application of a multiphase gas-liquid material (considered, in a first approximation, as a water-air mechanical mixture) as a relaxation medium that absorbs explosion energy and thereby reduces damage effect of a blast wave.
