doi:10.3969/j.issn.1000-1093.2016.08.028

Abstract

Abstract: 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.

Key words: petro-chemistry engineering, mobile pipeline, draining, gas-liquid two-phase flow, parameter, transient model
