CFD for Multiphase Flow Transport of Buried Crude Oil Pipeline Leakage

Buried pipeline is a kind of engineering equipment. With the increase of the pipeline working time, buried pipeline spill, caused by the defects from corrosion, abrasion and other inevitable factors, occurs. With the study of leakage numerical simulation in buried pipelines, the authors can analyze the influence that single phase-flow, multiphase flow and phase transition of crude oil has on the leakage process, and determine the impact of the leak under the various factors on the earth temperature field to provide a theoretical basis for the thermal infrared detection and rapid repair of buried pipelines. The results show that different penetration process and different thermal conductivities lead to different trends of surface temperature under the two kinds of leak process conditions. Regardless of the phase transition of crude oil and considering phase transition of crude oil leakage, basically the penetration process and surface temperature trends are the same. However, latent heat of solidification during oil phase change process is released. Therefore, considering the surface temperature trends in the oil phase change, multiphase flow leakage process lags behind the oil phase change. The conclusions of this article are for guidance in buried oil pipeline leak infrared imaging detection and crude oil contaminated soil remediation reference.
