| Abstract: | The digital simulation and the experimental research of the heat conduction characteristics are completed for the cylindrical layered tube made up of different materials. A calculation model of heat load and an analysis model of temperature field are established. Three layered tube structures with different requirements are analyzed on the temperature distribution. An experimental method is introduced in the dynamic temperature measurement of the layered tube. The test results and the calculation results are very contiguous. In this paper , the guidance significances are given for confirming materials and structure parameters of the layered tube and for improving the high temperature lifetime. |
