A 3D Situation Prediction Model for Oil Spills and Diffusion from Onshore Oil Pipelines
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.
