Abstract
An investigation of the effects of pipe length on flooding during adiabatic air-water counter-current two-phase flow in inclined pipes of 16mm ID. was conducted experimentally. A constant electric current method and visual observation were utilized to elucidate the flow mechanisms at the onset of flooding. It was found that the pipe length influences the phenomena at the onset of flooding. Upper flooding moves to lower flooding as the pipe length decreases. In the range of pipe length tested, the upper flooding disappeared when the pipe length was 0.5m. The onset of flooding decreases as the pipe length increases.
