Abstract:
The dynamic cool down during the transportation, the static cool down during the shut-down and the start-up of the oil in the pipeline in the field can be effectively simulated on the experimental loop(EL) ? There are some considerable issues unsolved such as the development of the oil temperature field in the pipeline and the relation of the cool down rate between the oil and the wall. Dynamic and static cool down process in experiments are numerically simulated using FLUENT. The simulated results show that under the cooling rates chosen in the experiments, the difference between the average temperature of oil in the pipeline and the pipe wall temperature during the dynamic cooling is within 0.16 t,and also the temperature difference during the static cooling is within 0.05 . Therefore, the temperature of the oil in the same cross sec-
