摘要
本文用迎流有限元方法模拟舟山内海域的潮流,在验证基础上计算了油泊位排放的含油污水对环境海域水质的影响。通过Lagrange无质量标记点跟踪计算,文章给出了在潮汐和风海流共同作用下,突发性溢油油膜中心点的运动轨迹,进而计算预测了溢油经历不同时刻后的弥散面积和影响范围。
This paper adopts an upstream FEM of 2-D unsteady flow to calculate the tidal flow in Zhoushan sea area. Based on Verification of the tidal current and environmental situation, the effects of oily waste discharged from the oil berths on the water quality have been calculated. The moving locus of the slick centrepoint of oil spill and its spreading area have been calculated. The results indicate that the set of model can predict the transport of oil spill in the Zhoushan sea area over a relatively short period of time with reasonable accuracy.
