摘要

为了研究管道系统严重段塞流的瞬态特性，以下倾管-立管系统为建模对象，建立了气液两相严重段塞流的一维数值模型。该模型基于分层流理论和分相流理论，分别对严重段塞流的四个阶段（液塞形成、液塞流出、液气喷发和液体回流）进行理论建模。模型的仿真结果与文献中的实验数据相对误差在10%以内，验证了该理论模型的有效性。在此基础上，对严重段塞流现象进行了数值仿真，并分析了气液折算速度对严重段塞流瞬态特性的影响。结果表明：下倾管-立管系统严重段塞流现象具有明显的周期特性，并且周期随着气相折算速度的增大而减小；立管底部压力波动幅值随着气相折算速度的增大而增大。研究结果可为管路系统的设计和振动预防提供参考。

Abstract

To analyze the transient characteristics of the severe slugging in piping systems, an inclined pipelinevertical piping system was chosen as a modeling object, and a onedimensional numerical model was proposed to simulate the gasliquid twophase severe slugging. According to the stratified flow and the separated phase theories and based on this theoretical model, the four stagesof the severe slugging—slug formation, slug production, blowout and liquid fallback were modelled respectively. The relative error of the model between the calculated results and the experimental data in published papers is less than 10%, which validates the efficacy of the theoretical model. On this basis, the numerical simulation on the severe slugging phenomenon was conducted, and then the influence of the gasliquid inflow superficial velocities on the transient characteristics of the severe slugging was analyzed. The results show that the severe slugging phenomenon is obviously periodical in the inclined pipelinevertical piping system. With the increase of the gas superficial velocity, the period of the severe slugging decreases, while the pressure fluctuation at the bottom of the vertical pipe increases. The research results can be a reference for the system design and vibration prevention of piping systems.
