Behaviours of Bubbles in Gas-Solid Fluidized-Bed

open access: yesChemical engineering, 1965
写真撮影, X-ray撮影, 電気容量法を用いて. ガス系流動層において発生する気泡の大きさ, 形, 上昇速度.気泡内の状態をしらべた.気泡はspherical cap型をしており, 内部には粒子ははとんどふくまれていない。気泡は, 他の気泡により上昇速度に大きく影響を受けるが, だいたい気泡の垂直方向の大きさの平方根に比例する上昇速度で上昇し, 会合, 分散をくりかえしながら大きくなっていくことがわかった。
