偏平な長方形細管内空気-水二相流のホールドアップと摩擦圧力損失の整理式 : 鉛直上昇流と水平流の比較(流体工学,流体機械)

Both vertical upward and horizontal gas-liquid two-phase flows in a flat capillary rectangular channel were studied to clarify the flow phenomena, i. e., the velocity and the passing frequency of liquid lumps, the holdup and the frictional pressure drop. The dimension of the channel used was 9.9mm×1.1mm. The orientations of the channel were the wide side vertical and the wide side horizontal in horizontal line. The differences between the flow characteristics in such orientations were investigated. New correlations of holdup and frictional pressure drop for flat capillary channels were proposed, in which the effect of aspect ratio has been taken into consideration.
