Modelling two-phase jets for hazard analysis

Abstract Hazard analysis of storage or transport of pressurised chemicals requires mathematical models of the behaviour of two-phase jets. In the past different models have highlighted different aspects of the problem. Here we shall review the most important factors in modelling two-phase jets, illustrating the problems with a simple analytical model and with results from the computer code trauma . Among the most important factors to be modelled are gravitational spreading, deposition of liquid, ambient air flow and ‘transition’ to dense gas dispersion.
