Simulation of Submarine Pipeline Oil Spill Based on Wave Motion

In order to explore the motion law of oil spill to conduct cleaning, simulation for submarine oil spill based on wave motion is carried out by user defined function and volume of fluid in FLUENT, and the dispersion and diffusion of oil spill in deep sea is simulated dynamically. Also the oil spill processes with different wavelength and current velocity are compared and analyzed. The results show that wave and current have important effects on the location and oil film area on sea surface. With wavelength increasing, the water depth influenced by wave, the scope of oil dispersion underwater and the oil film area on surface increase, respectively. With current velocity decreasing, the oil film area on sea surface, the distance between the oil film and oil spill source increased.
