Popis:	The effectiveness of a system designed to remove leaking oil from maritime accidents and prevent oil spill formation is examined. The leaking oil is collected by an inverted funnel (dome) and is channeled along with sea water, through a long riser tube to the sea surface, forming a two-phase buoyancy driven flow. It relies on gravity to channel the flux of oil towards the surface due to the fact that leaking oil does not dissolve and is of lower density than sea water. Through the 3D numerical study of the behavior of a quantity of oil trapped in the riser tube of the system, which is the worst case scenario, it can be decided whether the oil should be pumped out or it can be released due to buoyancy after the Rayleigh-Taylor instability expected to occur at the interface between oil and sea water.
