摘要:

针对严重段塞流的周期特性,通过下倾?立管实验系统进行了实验研究。基于实验数据及管内压力变化情况,分析了严重段塞流周期的变化规律,并与计算模型结果进行了相互验证。结果表明,在不同的下倾管倾斜角度、气相折算速度或液相折算速度等实验参数下,管内的流动状态会发生变化;由于立管高度不变,液塞喷发和液塞回流的时间基本不变,因此严重段塞流周期主要由液塞形成和液塞出流组成,且主要受下倾管倾斜角度、气相折算速度或液相折算速度等参数的影响。

Abstract:

Aiming at the periodic characteristics of severe slug flow an experimental study was carried out through the downward?riser system. Based on the experimental data and the variation of pressure in the pipe, the variation rule of the severe slug flow period was analyzed and verified reciprocally with the calculation model results. It turned out that the flow state in the tube would change under different experimental parameters such as the inclination angle of the downdip tube, the gas phase conversion velocity or the liquid phase conversion velocity. The time of the slug eruption and slug reflux was basically changeless on account of the height of the riser was invariant, so the period of severe slugging depends on the time of slug formation and slug outflow stages. And it was mainly affected by the inclination angle of downward riser, gas superficial velocity or liquid superficial velocity.

Key words: Severe slug flow, Gas?liquid transportation, Composite pipeline?riser system, Experimental study
