摘　　要：排空是野战输油管线的一项常规作业,为了提高排空作业的科学性和效率,建立了野战输油管线排空过程的瞬态模型,模型包括气体运动方程、液体运动方程以及相界面的耦合方程,并采用有限体积法对模型进行求解。在空压机排气压力和排气量给定的情况下,利用该模型可以计算出排空过程的管内各点压力、流量和持液率等参数。通过与实验参数对比,表明该模型计算精度较高,可以用于排空过程的管线运行参数预测,为排空设计和操作提供参考依据。Draining is a routine operation of mobile pipeline. A transient model of mobile pipeline draining is established in order to improve the scientificity and efficiency of draining operation. The proposed model consists of gas kinematic equations,liquid kinematic equations and interface coupling equations.The finite volume method is adopted to solve the model,which can calculate liquid holdup,pressure and flow rate in the case of the given initial pressure and flow rate of air compressor. The accuracy of the proposed model is verified by comparing the calculated results with the experimental parameters. The result shows that the proposed model has higher calculating accuracy,and could be used to predict the parameters of pipeline operation.
