文章根据热油管道停输后油品和管道周围土壤热力工况变化情况,提出了传热定解问题,并对其进行了一定的数学求解,得出了管道中各截面油品温度沿径向及随时间变化的解析解。该方法为更合理地确定管道在不同季节的安全传输时间提供了计算依据。
According to the change of thermal condition of oil and soil around pipeline after the shutdown of hot oil pipeline, this paper puts forward the problem of heat transfer solution and solves it by some mathematics, and draws the conclusion that the temperature of oil in each section of pipeline Analytical solution to and over time. This method provides a basis for more reasonable determination of the safe transmission time of pipelines in different seasons.
