【摘要】 为研究岸边排放溢油污染事故中的溢油轨迹,以水库岸边突发排放溢油污染事故为例,选取典型工况,首先通过三维水动力模拟,分析水动力特征;其次,利用改进的油粒子模型,通过质点示踪迹线分析油粒子在水平和垂向的迁移规律。结果表明,水平上,随着溢油的迁移,油膜面积逐渐变大;垂向上,油膜污染团中心垂向浓度分布逐渐趋于均匀。研究方法完善了溢油污染事故应急体系,对处理同类溢油污染事故具有指导意义。更多还原

【Abstract】 In order to study the oil spill trajectory in the oil spill accident on the shore,the sudden oil spill accident on the shore of the reservoir is taken as an example.To select the typical working conditions,first of all,three-dimensional hydrodynamic simulation is used to analyze the hydrodynamic characteristics.Secondly,the improved oil particle model and the trace line of the particle are adopted to analyze the migration law of oil particles in the horizontal and vertical direction.The results show that the oil film area gradually becomes larger with the migration of oil spill,and the vertical concentration distribution of the center of oil membrane fouling tends to be uniform gradually.This research method perfects the emergency system of oil spill accident,and has the guiding significance for dealing with the similar oil spill accidents.更多还原
