海上溢油行为与归宿的数值模拟研究

ccurately predicting the trajectory and fate of spilled oil at sea plays an important role in oil spill emergency response decision-making. This paper presents an oil spill trajectory and fate numerical model which was developed based on relative research at home and broad. In the model, the current fields generated by a three-dimensional hydrodynamic model are used as input data, the spilled oil are represented by a number of oil particles, and each oil particle is transported and diffused due to sea surface wind and current, and the weathering processes such as evaporation, emulsification, dispersion, dissolution, changes of density and viscosity are also included. To realize the effective numerical models data management and result visualization, a spilled oil simulation information system was also developed using VC++ and with application of geographic information system (GIS) and database techniques. The system was applied to simulate the “Zhuhai 3.24” oil spill accident happened in the Pearl River Estuary, the simulated current field was validated with the measured data, and the simulated spilled oil trajectory is in agreement with the observed data.
