Abstract: An experimental investigation of the air transport in a continuous twophase, air-water flow in downward inclined pipes is presented. The results relate to large pipes or conduits with inclinations between 0.004 ≤ S ≤ 0.087 and moderate water velocities. The following items were addressed: flow pattern and bubble shape, air transport capacities in continuous air-water flow and maximum air transport capacity. For a given pipe inclination and dimensionless water velocity there is a maximum air transport capacity for air transported with the water flow.
