Numerical Simulation of Oil Pipeline Leakage Diffusion in Dashagou Yellow River Crossing Section by Shaokang Liu, Mingyang Qiu, Guizhang Zhao, Menghan Jia, Jie An, Xi Guo, Dantong Lin, Yangsheng Tian, Jiangtao Zhou

“…In this study, the ANSYS 2020R1 software simulation is employed to examine the diffusion process of oil leakage and the underground water solute transport law in the Dashagou Yellow River crossing section of the oil pipeline. The simulation results demonstrate that under identical leakage pressure conditions, diesel fuel leakage in powdery, sandy soil is diminished, the emergency window is extended, and the corresponding leakage risk is reduced. …”
