Simulation of Leakage Model of Long-Distance Oil Pipeline Based on FLUENT

Based on the oil flowing state and the state equation of the long distance pipeline, the calculation method of leakage rate is analyzed when the pipeline leakage occurs. First, the leakage models of long-distance oil pipeline are established by FLUENT simulation, and the simulated results are close to the computed results, which prove the reliability of the simulation method, Then, through FLUENT simulating, the division of the models of the orifice leak, the macroporous leak and the pipe leak by the ratio of the leak-hole’s equivalent diameter to the pipe diameter is presented. Finally, the influence laws of the leak rates affected by the pipe diameter, the leak-hole’s equivalent diameter and the oil flow rate are investigated.
