摘要
基于CFD模拟,刻画了湿天然气集输起伏管道中积液的形成以及运移过程,实现了对上倾管液塞流动细节的准确描述。地形起伏管路中积液运移与气速和液相含率有关,在研究工况范围内,当气体流速大于5 m/s时,上倾管段基本不会形成液塞,起伏管整体携液表现较好。低液相含量条件下,液塞仅存在于起伏弯管最低点附近,不会向上倾管段持续生长。
Based on CFD simulation,the formation and migration process of liquid loading in a single undulating pipe is described,and the flow details of updip pipe liquid slug are accurately described. The migration of fluid accumulation in topographic relief pipeline is related to gas velocity and liquid holdup. In the range of working conditions under study,when the gas flow rate is greater than 7 m/s,the updip pipe segment basically does not form a liquid plug,and the overall fluid carrying performance of the undulating pipe is better. Under the condition of low liquid content,the liquid plug only exists near the lowest point of the undulating bend,and the upward inclined pipe section will not continue to grow.
