Abstract
Characteristics of the surrounding liquid motion of single rising bubbles were experimentally investigated. Three kinds of bubbles were generated and highly controlled by bubble generator. The motion of a bubble was captured by high-speed video camera using LEDs. In addition, surrounding liquid motion was visualized by PIV measurement. From PIV result, vorticity distribution and standard deviation of liquid-phase velocity were calculated. As a result, as increasing the bubble radius, the area of disturbance region increases. In addition, the shape oscillation of zigzagging bubble is a dominant factor for the standard deviation of the velocity fluctuation of surrounding liquid motion. On the contrary, the magnitude of the liquid disturbance induced by bubble increases as decreasing the bubble motion.
