本文介绍了一个模拟海上溢油的双层模型。该模型认为，海洋中的油由表面浮油和在流动深度上夹带的悬浮油滴组成。该模型是基于粒子的方法。释放到海洋中的石油数量分布在大量单独跟踪的颗粒中。它们在水面上时受水流和风致速度的驱动，湍流扩散也被考虑在随机游走技术之后。该模型包括许多重要过程：平流、表面扩散、蒸发、溶解、乳化、湍流扩散、浮油与海岸线的相互作用、沉积以及油的粘度、密度、表面张力等的时间变化。给出了渤海溢油的样本模拟。
In this study, a description of a two layers model for simulating oil spills in seas has been given. This model considers the oil in seas as consisting of surface oil slick and suspended oil droplets entrained over the depth of the flow. The model is based on the particle approach. The amount of oil released in seas is distributed among a large number of particles tracked individually. They are driven by water current and wind-induced speed when they are on the water surface and turbulent diffusion is also taken into account following a random walk technique. The model includes many significant processes: advection, surface spreading, evaporation, dissolution, emulsification, turbulent diffusion, the interaction of oil slick with the shoreline, sedimentation and the temporal variations of oil viscosity, density, surface-tension, etc. Sample simulations for oil spill in the Bohai Sea are presented.
