对于顺序输送,目前通常采用以平均流速代替管道的实际运行流速来计算混油量,在流量变化较大的情况下这种计算是不准确的。提出了一种交流速下混油量的计算方法,该方法考虑了管道实际运行过程中流速的不规律变化,在一个较小的时间步长内计算混油的增加量,再进行数值积分,最终得到油品运行时间内的总混油量。 For the order of delivery, the current average flow rate is usually used to calculate the actual flow rate of the pipeline to calculate the amount of mixed oil flow in the larger changes in the case of such calculations is not accurate. A method for calculating the amount of mixed oil at AC speed is proposed. This method takes into account the irregular change of flow rate during the actual operation of the pipeline, calculates the increase of mixed oil in a small time step, and then integrates the numerical value. Eventually get the total amount of oil mixture running time.
