摘要

Patterns of bubble attachment to the sliding gate were correlated as functions of the sliding gate opening, b, water flow rate, Q_L, gas flow rate, Q_g, and the wettability of the sliding gate. The patterns were classified into steady and periodical attachment types. As the wettability of the sliding gate becomes poor, the bubble attachment is promoted. The area of the bubble attachment region is also increased. Periodical bubble attachment to the sliding gate was observed under certain conditions. The period of the periodical bubble attachment increased with an increase in water flow rate, Q_L, for theta_c=61 deg and 107 deg, while it decreased with Q_L for theta_c = 144 deg.
