| Abstract: | A three-dimensional photographic method has been developed to measure phase distributions in bubbly flow in a pipe. In this
method a mirror was used to reflect a side view of the flow into the front-view direction, and then flow images in both views
were taken simultaneously by one camera. After three-dimensional position and size of each bubble in the flow field were determined
by matching the two bubble images in the side and front views, the phase distributions were obtained for the bubbly flow.
