A companion paper presented the development of a three-dimensional numerical model to simulate the behaviour of buoyant oil jets that result from underwater accidents. The numerical model was developed based on a Lagrangian integral technique. The model can simulate the behaviour of oil in stratified or unstratified ocean environments. The presence of a multi-directional ambient current is considered. The fluid in the buoyant jet can be a liquid, gas. or liquid/gas mixture, which is typical of many underwater oil-related accidents. The model formulation includes the diffusion and dissolution of oil from the jet to the ambient environment.
