Numerical Simulation of Leakage of Oil in a Submerged Duct and the Behavior of Oil in a Marine Environment

Abstract:

Oil spill at sea by pipeline cracks can cause environmental damage. Knowledge of interfacial phenomena of immiscible liquids helps to study the dispersion of pollutants in oceans, favoring thus flow behavior of the forecast in the vicinity of the leak in submerged pipelines. This study aims to numerically study the leakage of behavior in a submerged pipeline carrying oil. It adopted a two-dimensional model based on mass conservation equations, linear momentum and the model k-ε standard turbulence. We used the Ansys CFX for meshing with 40,510 hexahedral elements. The results of pressure fields and volumetric fraction of oil are analyzed and discussed.
