【Abstract】 The thermal analysis of buried steam pipelines were made and the physical model of buried steam pipeline was established.By simplifying the physical model,build up a three-dimensional mathematics model of the earth temperature field.CFD(Computational Fluid Dynamics)software does the numerical calculation of the buried steam pipeline temperature field and makes some objective analysis.The result tells us how to find the invalidation of the heat insulator with the infrared image technology.更多还原
