Abstract

The center-of-gravity and interface motion of a bubble are essential for deep understanding of mass transfer mechanism between gas and liquid phases in a bubble column, a gas-lift reactor, and so on. The aim of the present study is to quantitatively clarify the effect of a Surface Active Surfactant on the center-of-gravity motion of a single rising bubble. The single bubbles of about 2.7mm in equivalent diameter were examined. The center-of-gravity motion of the single bubbles has been visualized from two directions intersecting perpendicularly mutually, using two sets of high-speed video camera. In change of the zigzag cycle and amplitude of the rising motion, singular points have been discovered at a certain concentration. At the concentration, the amplitude of the zigzagging motion increases ; while the frequency decreases.
