摘要
管道瞬态水力计算可以采用特征线法,但其模拟结果的精度取决于管道沿线摩阻系数的选取。为缩小管道摩阻系数理论计算值与实际值存在的较大差异,对比分析了兰成渝成品油管道相关运行参数,指出采用辨识法确定管道各管段的摩阻系数,可以有效提高管道瞬态水力计算的精度。
Characteristic method is the general way to calculate the transient pressure and flow of pipeline,and accuracy of result depends on the calculation of friction factor of the pipeline.Due to the differential between the physical parameters used during the computation and real ones of the pipeline,detract always happened.In the hydraulic computation,this paper applies the identification method to friction factor calculation and gets better result.
