A vertical test channel made up of two subchannels simplifying a triangle tight lattice rod bundle was newly constructed, and experimental data were obtained on turbulent mixing rate between the subchannels. Experiments were conducted in various single-phase and two-phase air-water flows under the hydrodynamic equilibrium flow conditions. The present mixing rate data were compared with those reported so far for triangle lattice rod bundle channels as well as square ones, having hydraulic diameters of about four times larger than the present tight lattice channel. It was found that the mixing rate was considerably smaller in the present channel than the previous triangle and square lattice channels, i.e., a channel size effect.
