In order to increase void fraction and pressure drop data in a multi-subchannel system like an actual fuel rod bundle, air-water experiments have been conducted with a vertical 2×3 rod bundle channel made up of two central and four side subchannels. Experimental data on the void fraction, the pressure drop and the frictional pressure drop in each subchannel was obtained. The results show that both the void fraction and the frictional pressure drop are higher in the central subchannel than the side one. In the analysis, the data on gas and liquid flow rates in each subchannel was used, and the calculations by various correlations reported in literatures have been compared with the present data for validation. Results of such experiments and analyses are presented and discussed.
