摘　　要：建立了架空管道和埋地管道启输时的物理模型和数学模型;对架空管道和埋地管道启输过程进行了传热分析与数值模拟;通过实验结果验证数值模拟结果的准确性,得出启输过程传热规律。The physical and mathematical models of both buried and aerial pipelines were built. The thermal analysis and the numerical simulation were carried on during the start-up of the pipelines;the calculated results were contrasted with the experimental ones to enhance the ealculation precision. Then, the regulation of heat transfer during the start-up of pipelines was acquired.
