The purpose of this work is to propose an experimental method of a two-dimensional (2-D) two-phase gas-liquid flow. A test channel in which a nearly 2-D, uniform two-phase flow can occur was made. This channel was a vertical, narrow gap space made up of two large concentric pipes. A two-phase air-water flow around a body mounted in the channel was recorded consecutively by a high-speed TV camera, and its void fraction distribution was determined using image processing. Several results for flows around a flat plate, and flows along a straight wall and flows between parallel walls were obtained.
