Numerical Simulation on the Thermal and Hydraulic Behaviors of Batch Pipelining Crude Oils with Different Inlet Temperatures - An unsteady hydraulic and thermodynamic model is proposed to describe the heat and fluid flow characteristics of batch pipelining of crude oils in buried pipeline with different inlet temperatures, and the control volume method combined with finite difference method is used to discretize the governing equations. The numerical model and computer code are verified by field test data of a pipeline in China, and the resulting simulations are in good agreement with experiments. The periodic behaviors of heat flux density, oil temperature, heat storage of soil and friction loss are presented and explained, and the strong coupling relations within them are clarified. For two kinds of crude oils transported in batches, three heating schemes are proposed and the economy and safety are evaluated. The simulation results show that the heating scheme, in which only a small portion of the low-pour-point crude oil just traveling before the high-pour-point crude oil is heated and all the high-pour-point crude oil is heated to a uniform temperature, costs the smallest heating energy.
