| Abstract: | A mathematical model was established for describing the cooling proccss ofunderwater or overhead crude oil pipelines after shutdown, A numerical solution of the modelwas obtained by using finite element method. The free convection problems of crude oil underthe conditions of phase change and moving boundary were well solved. The comparisonsbetween numerical and experimental results show that the model is satisfactory for predictingthe cooling process of the underwater or overhead crude oil pipelines after shutdown. |
