摘要:
采用主管水平、支管垂直向上的T 形管, 以空气和水为介质, 在层状流和塞状流条件下, 测定了气液两相流的分离数 据。用传统方法及分离效率指标评价了T 形管对两相流的分离结果。层状流条件下的分离效果明显好于塞状流; 塞状流时, 主 管入口气体流速恒定, 通入主管内液体流速越小, T 形管的分离效果越好; 恒定主管入口液体流速, 在气体的采出分率达到 0.7 之前, 增加入口气体流速, 能提高T 形管的分离效率, 但0.7 之后, 增加气体流速对T 形管分离效率的提高不明显。实验 结果与先前研究者的经验关联式比较, 发现Seeger 等人的经验关联式给出了两相流在T 形管处相分离的趋势。
Abstract:
Separat io n of gas- liquid tw o phase f low at a T - junct ion w ith a ho rizontal main pipe and a vert ical ly upw ard branch w as invest igated under the f low pat terns of the plug and the st rat ified. T he separat ion data obtained by a series of ex periment s w er e evaluated by the t radit ional method and the separ at ion ef f iciency . T he separat ion eff iciency for the str at ified f low is much higher than that for the plug flow. A constant gas velocity w as fo und in the plug f low , the low er the liquid velocity, the higher the separ at ion ef f iciency ; at a g iv en liquid velocity, incr easing the g as velocity can improv e the separation eff iciency before the f ract ion o f gas takeof f reaches 0?? 7. In co nt rast , there is no ef fect w hen the f ract ion is abov e 0?? 7. The data w ere also compared w ith the pr edict ions obtained by previous correlat io ns. The Seeger??s equat ion gave ag reeable t rends.
