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。
Considering the tidal current of M2,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.
