Hydrogen energy attracts attention as eco-friendly energy recently. Especially the fuel cell vehicle that uses hydrogen as fuel will be expected as a post gasoline car in the future. However, since hydrogen gas can burn in mixtures with air from very lean to rich, when hydrogen gas leaked from hydrogen refueling station, the danger of causing explosion is high. Therefore, it is necessary to design so that the serious damage for the windowpane and a human body may not be given in case of emergency accident. So, it is important to predict the blast pressure correctly at the time of explosion. But, an explosion experiment has some problems of a site, time, and cost, so that the numerical simulation is needed for highly precise prediction. In this study, we simulate the hydrogen explosion experiment conducted in the past and verify the prediction accuracy.
