| Abstract: | In view of super heavy oil buried pipeline high temperature transportation＇s characteristic,steady state heat transfer model of the hot oil transportation pipeline was established.Taking into account the influence of natural convection heat transfer on the temperature field distribution,the pipeline temperature field before and after invalidation of heat insulator was numerically simulated and analyzed by CFD software,which can provide the theory instruction for the pipeline safe examination in certain extent. |
