SUMMARY

This is Volume 2 of the final report of the Buncefield Explosion Mechanism Phase 2 Joint Industry Project, which further investigated the 'Dispersion and Explosion Characteristics of Large Vapour Clouds'. The project’s ultimate objectives were to understand vapour cloud development following large losses of primary containment, the characteristics of explosions involving large flat flammable vapour clouds and the explosion mechanisms that can give rise to very high overpressures over a large area as observed in the Buncefield incident. This has been done through large and medium scale experimental studies supplemented by numerical analysis.

The project report is divided into two volumes. Volume 1, which is available separately, provides an overview and a summary of the work undertaken, the results and the main findings. Volume 1 draws from the content of this report, Volume 2, which contains the final reports of the individual studies performed as part of the project.
