摘要：according to the characteristics of waxy crystal phase change during waxing process of crude oil, a novel model that was a wide phase transition interface partition model was established, and the equivalent specific heat capacity method was used to deal with latent heat problem. The governing equations for each partition were proposed. Compared with the experimental data, the maximum relative error was 3.41%, and then the model was used to analyze the heat transfer process of oil phase change. The research results can provide important theoretical support for the practical application of overhead pipeline shutdown and maintenance.
