Numerical Study of Leakage and Diffusion of Underwater Oil Spill by Using Volume-of-Fluid (VOF) Technique and Remediation Strategies for Clean-Up

An oil spill accident will cause serious harm to marine ecology and the environment. Rapid response effective prevention methods are required minimize damage of accidents. The critical problems that emergency rescue teams face when spilled reaches sea surface, extent oil, how far they from drilling platform. However, there is no reliable model predict diffusion distance oil. Accurately predicting characteristics underwater can provide timely accurate information for treatment accidents guide correct implementation treatment. In this paper, computational fluid dynamics (CFD) method was used establish a two-phase flow submarine spill. volume-of-fluid (VOF) technique implemented track interface between oil–water phases. effects different parameters on leakage were investigated by adjusting velocity, ocean current crude density, viscosity. logarithmic velocity profile adopted currents conform actual near surface. A user-defined function (UDF) developed applied CFD modeling. focus analyzing range (rising height Hp lateral migration Wp) full-field data. results indicate viscosity impact viscous shear force, spill’s inertia effect. formula calculating under working conditions obtained fitting. study scientific basis formulating an plan offshore minimizing
