Summary:Energy delivering pipes which are buried in the ground will change the surrounding temperature field accompanied by energy loss. This paper established the two-dimensional temperature field mathematical model of the soil around the underground burying pipes, and simplified the third order boundary condition as the first kind of boundary condition by adopting the hypothesized surface law. Besides, it solved the temperature field of the soil around the underground burying pipes by adopting the principle of superposition, the variable resolution and the hypothesized heat source law, and has further analyzed the heat transfer process of the underground burying pipes under the effect of double heat source of the atmospheric and the soil stratosphere, as well as the fluid temperature field along pipes. This paper provides thermal reference for engineering design of underground buried pipe.
