An experiment was conducted in order to investigate the flow behavior for an air-water two-phase flow in a vertical pipe rotating with it's own axis. From flow visualizations, it is found that a unique flow pattern appears in the rotating two-phase flow as the bubbly slug flow which exists between the bubble flow and the slug flow modes, and it is revealed that these modes which are strongly influenced by the speed of pipe rotation have strong relation with the entering basic flow. Basic flow characteristics are much influenced by the rotation, followed by the reduction of the pressure drop and changes in the void fraction, depending upon the speed of pipe rotation and entering two-phase flow modes.
