摘    要:基于POM建立了M2分潮的大连湾海域三维潮流场动力模式。利用此动力模式,以"油粒子"模型来模拟溢油在大连湾中的漂移扩散过程。通过欧拉-拉格朗日法,将油膜中心的轨迹和各个时刻的油膜分布情况可视化。溢油预测模型综合考虑了三维流场、湍流、风导输移和波浪破等环境因素对海上溢油行为的影响,考虑了蒸发和乳化过程,预测了溢油的归宿。本模型旨在为大连湾海上溢油风险评价提供信息。

关 键 词:溢油  漂移轨迹  大连湾

Abstract:Considering the tidal current of M_2,the model of 3D tidal flow based on POM in Dalian Bay is built.Combined with this model,the drifting and diffusion processes were simulated based on the particle approach.Using the Euler-Lagrange method,the track of centre of the oil slick and the temporal dispersion scope visualized.This Oil-spill forecast model is used to supply 3-D flow field,turbulence,wind-driven transport and breaking waves as the environmental forcing of the behavior of oil-spill.Evaporation and emulsification processes are also considered.The end-result of oil-spill is predicted.This model can provide information for risk assessment of oil spill in Dalian Bay.
