螺旋管内油-水液液两相流流型

FLOW PATTERNS OF OIL-WATER LIQUID-LIQUID TWO-PHASE FLOW IN HELLCALLY COILED TUBES

在两种不同放置位置螺旋管内进行了油 -水液液两相流流型的实验研究 ,定义了各种不同流动条件下油-水两相流的流型 ,给出了螺旋管内液液两相流的流型图 .进而讨论了各流型之间转变的机理 ,并考察了螺旋管结构尺寸及放置方式对油水两相流流型及相转变特性的影响 .

In this paper an experimental research on the oil-water liquid-liquid two-phase flow patterns and their transitions in both horizontal and vertical helically coiled tubes is presented. The different flow patterns are defined and distinguished from each other according to the relationship between oil and water phase in the tubes. The flow pattern maps and phase inversion points are obtained and compared with the results in horizontal pipes. The effect of the dimensions and different locations of the helically coiled tubes on flow pattern transition and phase inversion point is also examined.
