• 20302 Change of a Single Rising Bubble Motion by Attachment of Surface Active Surfactant

抄録

The effect of a surfactant on the motion of a single ascending bubble was experimentally investigated using high-speed visualization in a 1-pentanol and purified-water system. The bubble-interface vibration is damped down with increase in the 1-pentanol mass concentration. Shifts of the amplitude and frequency of the bubble trajectory were quantitatively confirmed. The frequency reached the minimum at a 1-pentanol mass concentration of 200ppm ; after that, the frequency increased. Contrary, amplitude reached the maximum at a 1-pentanol mass concentration of 200ppm. Also, under a high concentration of the surfactant, the bubble drift motion was not observed any longer. Furthermore, the bubble motion is compared with the motion of a spherical solid particle which has no interface vibration. The drag coefficient of the bubble becomes closely similar to that of the solid particle in consequence of adsorption of the 1-pentanol on the bubble-interface.
