摘要: 针对河道型水库溢油模拟研究匮乏的现状,以龙溪口库区河道突发溢油事故的预测模拟为例,分别建立了传统费伊(FAY)模型及油粒子模型,力图探明这两种主流模型在求解狭长河段溢油扩散时的特性。研究结果表明:FAY模型侧重于油膜扩展阶段中油膜厚度的精细模拟,但在水文情势复杂的河道溢油模拟过程中没有有效考虑流场、风场、地形对油膜漂移、扩散的影响;油粒子MIKE21-OS模型则克服了上述不足,对于河道溢油的模拟具备一定精度。模拟结果可为龙溪口库区突发溢油事故的预测预警提供参考。

Abstract: There are few studies about oil spill simulation in river-channel reservoirs. This paper established the traditional FAY model and oil particle model for Longxikou reservoir to study the characteristics of oil spill in river-channel reservoir and the oil spill simulation differences between the two models. It is shown that FAY model has advantages in fine oil thickness simulation in oil film extension, but without consideration on the oil film extension influence from flow field, wind field, landform. MIKE21-OS model overcomes the above shortcomings and has higher simulation accuracy of oil spill in river channel and can provide good references for early warning and forecasts of oil spill accident in Longxikou Reservoir.
Key words: oil spill, FAY model, oil particle model, simulation of oil spill, Longxikou Reservoir
