CFD simulation of oil-water flow in a horizontal pipe

Water produced along with crude oil during production and transported together in a pipeline is a common occurrence in a petroleum production system. Understanding the behaviour of crude oil-water flow in a pipeline is crucial to many engineering applications, such as design and operation of flowlin...
