摘要
研究东中国海中日共同开发区附近海域溢油污染的问题,在模拟水动力场的基础上模拟了海上溢油漂移扩散情况。在表层流场和风场的作用下漂移,而油膜的扩展则通过油粒子的随机走动来实现。本文以东海西湖凹陷原油为溢油油种,通过模拟分析不同季节和不同风况下的溢油事故,对溢油油膜的扫海范围进行了分析。
An oil particle-tracing model was built to simulate the pollution of oil spill in the East China Sea. Based on the tidal-current numerical simulation, oil-spill drifting was simulated. The model dispersed the oil slick into a lot of oil particles, and each of them re- presented certain quantity of oil. The transport was driven by the surface-layer current and wind. And the spreading of the slick can be simulated through the random-walking of oil particles. In order to simulate the oil slick drifting track and sweeping range, the crude oil from Xihu Trough was chosen as oil-spill kind under different wind situation in different seasons.
