| Abstract: | Three-dimensional (3D) trajectories of spherical air bubbles passing through a converging part of a rectangular channel have
been measured. Bubble diameters, d
b, were less than 1 mm and the Reynolds numbers, Re
b, for stagnant tapwater and for mean liquid velocity vˉ
L=0.25 m/s were in about same range.
