Abstract:
The thermal conditions for buried oil p ipelines were evaluated. The physical model and mathematical model for buried oil p ipelines were established. Computational fluid dynamics software has worked out a numerical calculation method for buried stealing p ipeline. The temperature field of buried oil p ipeline was quite obvious in the ground region, and the temperature of buried oil p ipeline is obviously high in the ground track region. An infrared image localization experiment plan of buried oil pipeline ismade, experimental tests conducted, p roving that the temperature field distribution in ground heat

affected zone of the oilp ipeline is not very even. The simulation computation and the experimental study contrast indicated that the ground region temperature field of buried oil p ipeline tallies both the simulation situation and the actual situation.
Key words:
buried oil p ipeline; CFD numerical calculation; orientation; temperature field; infrared image
