アイススラリーの流動様相に及ぼす気泡と液相濃度の影響

抄録

It is known that the flow pattern of ice slurry containing bubbles in the liquid likely to become homogeneous flow. It is also known that flow pattern of ethanol solution ice slurry is changed by agglomeration of ice particles occurring when the liquid phase concentration is less than 3wt%. In this study, we investigate the effects of bubbles and liquid phase concentration on flow pattern of ice slurry made from ethanol solution of 3wt% and 5wt%. The experimental results confirm that the bubbles have a dispersing effect on the ice particles. The effect is present at all liquid phase concentrations, and the effect is higher at lower liquid phase concentrations.
