This paper describes the development of a comprehensive numerical methodology designed to evaluate the vulnerability of offshore platforms to detonations resulting from the accidental release of hydrocarbon gaseous clouds. The numerical simulation of such explosions requires simulating such varied physical phenomena as deflagration to detonation transition, detonation wave diffraction about many structural components, and structural response to blast loading. Hence, to completely assess and quantify safety and explosion hazards, it became necessary to integrate state-of-the-art methodologies from such widely disparate fields as computational fluid dynamics (CFD), computational structural dynamics (CSD), and detonation physics. The development of this couple methodology was recently completed. To demonstrate the capability of the new methodology to model detonation wave diffraction within large, complex geometry structures similar to offshore platforms, The authors include here the results of two studies: blast diffraction within the World Trade Center and within a civilian jumbo jetliner. In addition, to demonstrate the ability of the new methodology to model hydrocarbon gaseous detonations, they include some recent results from a stability study of detonation wave propagation in a two-phase flow.
