S0501-2-2 CTAB水溶液の円筒内流れに対する塩注入によるゲル生成現象([S0501-2 ]複雑流体の流動現象(2))
詳細
In aqueous solutions of CTAB, worm-like micelles are formed at concentrations above CMC. In addition when counter ion is added to a CTAB solution, worm-like micelles entangle and form networks, which show gel-like structures under some conditions. In the present study, investigated is the formation of gel-like structures when an aqueous solution of NaSal is injected into a flow of a CTAB solution in a circular channel. The condition at which the adhesion of a gel to a channel wall occurs relates both the concentration of NaSal and the velocity of CTAB solution. When the concentration is high, the adhesion can be observed at higher velocity.
