摘要
为了评估陆上输油管道溢油的危害范围,以陆上输油管道溢油扩散事故为研究对象,设计三维态势推演模型.将计算得到的陆上输油管道溢油速度、溢油量等参数作为模型的输入项,设置质量守恒和动量守恒作为三维态势推演模型的约束条件.模拟陆上输油管道的溢油过程,在相关条件的约束下,实现横向扩散和纵向渗透的态势推演,综合考虑蒸发和吸附现象,调整态势推演结果,输出横向扩散范围、纵向渗透深度等参数的推演结果.通过模型分析实验得出结论:与传统推演模型相比,优化设计模型的横向扩散面积推演误差和纵向扩散深度推演误差分别降低约 3.57 m2 和 0.2 m,即优化设计模型在态势推演精度性能方面具有明显优势.
Abstract
For purpose of evaluating the hazard range of oil spills from the onshore oil pipeline,the oil spill diffusion accident of onshore oil pipeline was taken as the object of study,and a 3D situation simulation model was designed,in which,having parameters of oil spills'velocity and amount there calculated taken as the input items of the model,and the mass conservation and momentum set as the constraints of this model.In simulating the oil-spilling process,the situation of lateral diffusion and vertical penetration was realized under the constraints of relevant conditions,including having the evaporation and adsorption phenomena considered comprehensively,and the situation results adjusted to output the simulation results of both later-al diffusion range and vertical penetration depth.The model analysis experiment indicates that,compared with the traditional simulation model,this optimal model can reduce the simulation error of lateral diffusion area and the longitudinal diffusion depth by about 3.57 m2 and 0.2 m respectively,which means that the optimized design model has obvious advantages in accurately simulating the oil spills and diffusion.
