Abstract:
Modeling of industrial accidents with liquefied toxic and flammable gases is considered. Propagation of non-reacting heavy gas clouds over complex terrains is described by a two-dimensional model with averaging over the cloud height. Numerical simulation of a toxic accident initiated by chlorine release in the urban environment has been performed and the number of injured people has been computed. A two-dimensional axisymmetric model based on the Favre-averaged Navier–Stokes equations is used to model the fireballs occurring upon combustion of hydrocarbon fuel-air clouds. Zones of various thermal hazards for people have been obtained.
Keywords:
industrial accidents, toxic and flammable gases, heavy gas clouds propagation, fireball, consequence analysis, numerical simulation.
