Experimental series of stratified gas-liquid two-phase flows had been carried\nout in a 26 mm i.d. transparent acrylic horizontal pipe. The study was aimed to\ndetermine the interfacial wave characteristics of the flow and to develop a\nhigh quality database of it. The longitudinal section of the pipe was used as\nthe reference section of image recording. Air and water were used as the test\nfluids, flowing co-currently inside the pipe. The flow behavior was recorded by\nusing a high-speed video camera around 5 m in axial distance from the inlet\npipe to ensure the fully-developed stratified gas-liquid two-phase flow. To\ncorrect the refraction due to the acrylic pipe, a correction box was employed\nin the visualization test section. The group of stratified smooth and wavy\ntwo-phase flows were successfully recorded and classified on the basis of the\nvisualization study from 24 couples of test condition of superficial water and\nair velocities. Digital image processing technique was then used to perform\nquantitative analysis and the results were used to evaluate the existing data.\nIn the present study, the image processing technique was performed to obtain\nthe liquid holdup distribution. The present results show satisfactory agreement\nwith previous works.\n
