The fluid flow resistance and the behavior of liquid film of an annular countercurrent two-phase flow are investigated experimentally in a wide range of flow pattern. Air and water are used for the two-phase flow. Water flows down along the inner surface of a vertical tube and air flows up, counter to the water flow in the tube. The fluctuation of the surface waves of the liquid film is amplified with increasing gas velocity and the waves develop into liquid bridges. Once the bridges are formed, the water is carried upward and flooding starts. The fluid flow resistance of the two-phase flow is approximately 2 times higher than that of the typical single-phase flow, and increases suddenly at 3 times the resistance of the two-phase flow at the beginning of flooding.
