Development of a model to predict the effects of explosions in compact congested regions

In this paper it is shown how a number of models can be produced and linked together to predict the consequences of a vapour cloud explosion in a compact region of congestion on a typical gas processing or storage site. The individual models address the generation of pressure within the congested region, the propagation of the resulting pressure wave away from the region and the load received by any obstacle on the site outside of the congested region. The performance of each of the models is illustrated and discussed, including comparisons with experimental data. Finally, the application of the models to practical cases is considered.
