Two-phase flow is the simplest phenomenon of multi-phase flow. Mini-pipe two-phase flow can be applied to high-density multi-chip modules on supercomputers, X-ray equipment, and other high-power diagnostic equipment, high-flux heat exchangers in aerospace systems, cryogenic cooling systems on satellites etc. The more widespread the application of two-phase flow on mini pipes in the industrial world, the experimental studies are needed in order to determine changes in flow patterns and flow pattern maps to variations in slope angle, viscosity value, superficial air velocity (JG), and solution superficial velocity (JL). The visualization method in this study used a Nikon J4 camera. The results of the videos obtained are then analyzed the shape of the flow pattern based on the values of JG and JL. Furthermore, it is mapped in the flow pattern map with JG as the x-axis and JL as the y-axis. The map of the flow pattern that has been formed is then compared with previous research to find out the changes that occur and complete existing data. The equipment and materials used in this study were glass pipes with a diameter of 1,6 mm and a solution of distilled water-glycerin with concentrations of 40%, 50%, 60%, and 70%. Variation of gas superficial velocity (JG) and superficial velocity solution (JL) in the range JG = 0 m/s – 66,3 m/s ; JL = 0,033 m/s - 4,935 m/s. In this study, there are five flow patterns: bubbly, plug, slug-annular, annular, and churn. Comparison of flow pattern maps in this study with maps of previous research flow patterns shows a shift in the transition line.
