Numerical Simulation Research on the Mixed Contamination Plug of Oil Product Batch Transportation Pipeline
The refined petroleum products pipeline operation was simulated to analyze the generation and development of the mixed contamination plug.The results showed that transporting the low viscosity refined petroleum products first can decrease the length of mixed contamination plug and reduce the economic loss;Increasing the flow velocity can lengthen the length of mixed contamination plug,and it has greater influence on the condition that transporting the larger viscosity refined petroleum products first;The transporting affection of the arc bend pipe is better than that of right-angel bend,and it can prevent the appearance of the washing dead zone and decreases the length of the mixed contamination plug.
