三峡库区溢油预报模型构建及数值模拟

Model Construction and Numerical Simulation for Forecasting Oil Spill in Three Gorges Reservoir Area

随着三峡库区通航条件改善和船舶流量的不断增加,库区水上溢油风险形势日益严峻。综合考虑风、流的作用,结合水动力方程、溢油漂移扩散的"油粒子"模型等,设计了适用于三峡库区船舶溢油预报模型,并从应急的角度出发,对水动力模型进行并行化改造,提高了预报速度。在此基础上对175 m水位库区的假想溢油事故进行了模拟,初步检验了溢油预测模型的效果。

With improvement of navigational environment and increase of water traffic in Three Gorges reservoir area,the risk of oil spill in this area is rising steadily.A model for forecasting oil spill is designed,which incorporates hydrodynamic model,oil spill particle drift model and the effects of wind and current.The model was used to simulate an oil spill case at Wanzhou section of the Changjiang River and the simulation results are analyzed.
