Considered influence of buried pipe

Considered influence of buried pipeline leakage of crude oil pollutants multiphase flow migration phenomenon effects, numerical model was established to buried pipeline road multiphase leak process simplified for two-dimension problem, numerical simulation was used with the CFD software FLUENT on buried pipeline leakage of crude oil pollutants migration process caused pollution problem, calculation simulation was carried out in the two species workers condition of one phase flow and multiphase flow buried pipeline leakage of pollutants around earth temperature field, the speed field and the distributions of oil/water phase in the soil porous media. Analysis the comparison of results indicated that: 1) the affected region of temperatures spread above the buried oil pipeline was more slowly than either side of the rate of diffusion;2) During the buried pipeline leakage early, except the maximum of velocity near the leakage mouth, the other penetration regional velocity of leakage crude oil are very low.
