Sensitivity analysis of crude oil’s physical properties to total freezing time

ABSTRACT
the physical parameters of crude oil are one of the main factors affecting the heat transfer of phase change. A mathematical model for a hot oil overhead pipeline was established, taking latent heat impact, the non-Newtonian properties of crude oil, and nature convection heat transfer into account. Compared with the experimental data, the model and the solution method were correct. And a criterion was made to estimate the crude oil total freezing in a pipeline by tracking the change trajectory of the maximum temperature point. The effects of the crude oil with average properties on the total freezing time in a pipeline were analyzed, and the sensitivity of the different influencing factors was investigated by orthogonal test.
