Reduction of Overpressure caused by Hydrogen Explosion using Protect Walls

Abstract

A purpose of this research work is to enhance the safety of hydrogen facilities such as hydrogen refueling stations. Characteristic of hydrogen explosion was studied using experimental data conducted by IAE and SRII, and numerical simulations of shock wave propagation by explosion were performed to study the effect of protective walls. Result of numerical simulations agreed well with experiments. As the result of simulations on various conditions, it was found that protective wall should have certain width at least 12 meters, and the reduction effect of explosion overpressure greatly depends on the height of the wall and it does not depend on its configuration.
