Abstract

The results of investigations in flow patterns of two-phase liquid-liquid flows in horizontal pipes with diameters of 12, 16 and 22 mm have been presented in the paper. 

Water and two types of oil, i.e., machine oil, Iighter than water, and tar oil, heavier than water, were investigated. As a result of conducted studies, the observed flow patterns were described, defined and named, moreover they were also systematized. The ranges of particuLar flow patterns have been presented in the form of flow pattern maps.
