The transport of oil and its derivates is mainly done through pipelines linking the oil fields, refineries and distribution networks to consumers. They are considered the best, safe and economical way to fluids transportation over long distances. Despite significant advances in the development of lighter and stronger materials for the construction of pipelines and the growing number of gas and oil pipelines, many problems of leaks have been observed, which has encouraged the development of reliable techniques to inspect and detect quickly and accurately possible leaks along these pipelines. The goal is to eliminate or minimize damage to the oil industry and mainly to the environment. In this context, this paper aims to study the thermo-fluid dynamics of a transient three-phase flow (oil, water and gas) in a horizontal pipe in the presence of a leakage at different positions. Herein it was applied a 3D Eulerian-Eulerian model, including the transient turbulent model (RNG k-ε), using the ANSYS CFX® 12.1 commercial package to perform all simulations. Numerical results of velocity, pressure and volume fraction fields of the involved phases are presented and discussed.
