Pressure-Oscillatory Defoaming for Shear-thinning Fluids

open access: yesKAGAKU KOGAKU RONBUNSHU, 2007
筆者らは,圧力振動場を用い,Shear-thinning性流体中の気泡上昇速度を促進させる方法を検討した.気泡が意図的に膨張・縮小するよう機械的に圧力振動させると,気泡近傍に強い局所剪断流れが生じる.その際,気泡近傍の局所剪断粘度は低下し,気泡上昇速度は促進される.この方法により,Shear-thinning性流体では,自然上昇速度と比較して,400倍を超える気泡上昇速度が得られた.一方,Newton流体では,促進効果はほとんど得られなかった.気泡近傍の剪断粘度を実験的に評価するため,ビデオとストロボスコープを用い,気泡径の時系列変化を調べた.ここで得られた剪断粘度低下から推算した促進効果は,実測値と良好に一致した.
