摘要:

本文采用三维元胞自动机模型, 对海洋溢油过程进行了模拟, 对风流、水流等水平方向的影响系数进行了改进。考虑了蒸发、垂直扩散、岸边附着、溶解、乳化等因子的影响, 并且引入乳化含水率将乳化因子进行实际量化, 构建了海洋溢油模型。并以“DeepSpill”的溢油实验为基础进行了模拟,实验结果Kappa系数达到0.902, 与实际相比具有较好的一致性。本文对海洋溢油事故进行预测模拟,为提出合理有效的应急预案提供科学依据。

Abstract:

Based on the three-dimensional cellular automata model, this paper studies oil spill. The influence coefficients of the wind and flow in the horizontal direction are improved, in addition to considering the influence of evaporation and vertical diffusion in the vertical direction; the shore attachment, dissolution factor, and the emulsified water content parameters are ased in order to achieve a practical quantitative emulsifying factor. Based on the experiment “DeepSpill”, the simulation precision is considerably improved.

Key words: cellular automata marine oil spill simulation
