英文摘要：

It is meaningful to study and gain a deep understanding of thermal and hydraulic phe- nomena,and it is important to develop better operation strategies to ensure operation safety.A mathematical model was established to study the hydraulic and thermal characteristic of buried hot oil pipeline under normal operation.An unstructured-finite volume method was used to discretize the governing equations.The agreement between numerical and experimental results is quite good.
