• An investigation of air-water counter-current two-phase flow in inclined pipe about flow patterns, the onset of flooding, pressure gradient and liquid hold-up were conducted experimentally. The pipe inclination angles examined were 30°, 45°and 60°from horizontal. The tube diameters were 16 mm and 26 mm I.D., the superficial velocities of air and water ranged from 1.0-25 m/sec and from 0.017-0.14 m/sec, respectively. As a result, it was found that (1) the flooding characteristics in counter-current two-phase flow in inclined pipe can be shown with variations of pressure gradient and liquid hold-up, where the pressure gradient was increased slowly in the pre-flooding then increased rapidly at the onset of flooding and gradually decreased in the post-flooding regime, while, liquid hold-up was decreased slowly in the pre and post-flooding regimes and increased rapidly at the onset of flooding, (2) an experimental correlation to predict the onset of flooding in inclined pipe was developed with error band ±10%.
