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., http://ci.nii.ac.jp/naid/110006187877@@@http://www.jsme.or.jp/}, pages = {133--134}, title = {二流体モデルを用いた垂直2×3ロッド流路内気液二相流のサブチャンネルボイド率と圧力損失の予測}, year = {2005}, yomi = {サダトミ, ミチオ and カワハラ, アキマロ} }
