The present study deals with the mathematical modelling of vented explosions of hydrogen. The main focus is on the realistic scenarios of flow past an obstacle which increase the observed peak pressure significantly. The framework of a basic model is described first. Then formulation to account this obstacle is given in detail and validations from recent experiments on a 20-foot ISO container are shown. The model predictions match well with the experimental results for various model obstacles in different configurations.
