The concurrent vertical upward flow of air and water has been made at various rates and ratios of air to water in a 2 1/8‐in. × 20 ft. open transparent Tenite tube as well as in a 1 5/16‐in. × 2 1/8‐in. annulus. Pressure drops and in‐place ratios of gas to liquid have also been observed in order to correlate such data with corresponding flow types and patterns. Motion pictures taken at normal and especially those at high‐speed have made it possible to see flow mechanisms indistinguishable to the naked eye.
