| 摘 要： | 在含蜡热油管道的实际运行过程中，油品的一些物性参数，如比热容、黏度、密度等均随油温的变化而变化。在加热站间管道沿线，流态和流型随着温度的变化也会发生转变。综合考虑以上因素，采用数值积分方法，对加热站间管路划分了区间，各自应用不同的摩阻特性公式进行摩阻损失计算，提高了计算精度。

| Abstract: | In waxy hot oil pipeline process,oil physical performance parameters,for example,specific-heat,viscosity and density changed with temperature drop.Flow profile and flow type also transited along pipeline inter thermal stations.Taking into account those influence factors,the pipeline inter thermal stations was divided into parts,different hydraulic resistance formulae were selected according to these parts and accuracy of numerical solution was improved. |
