Abstract

Marine oil spills can cause serious damage to the marine ecological environment. In the numerical modeling of oil plume rising and its advection, a better understanding of the oil plume transport may be effective on the sea pollution reduction and removing pollutants. In this paper, the effects of waves are investigated on the oil plume convection-diffusion pattern using smoothed particle hydrodynamics (SPH). Firstly, the rising patterns of an oil plume of different densities are simulated and the results are compared with the analytical solution. Then, the concentration distribution is shown for the oil plume rising problem. Afterwards, the suitability of the SPH method is examined by a cnoidal wave on shore effect. Finally, the plume of different conditions is located in waves and the advection of pollutant is studied with a fixed boom and different angles. It will be concluded that using a boom with a zero diversion angle would lead to minimum passing pollutant.
