b Risk analysis of near-surface vapour cloud explosion basing on its fluid dynamics consequences G.M. Makhviladze*, J.P. Roberts*, S.E. Yakush* & B.E.

Three major accidents involving hydrocarbon vapour cloud explosions are compared from the viewpoint or their effects and con- sequences. Importance of taking into account the fluid dynamics of vapour cloud combustion and the strong afterwinds generated by the fireball is demonstrated by case history studies and by mathematical modelling of the unconfined fuel cloud behaviour and deflagration.
