Moving Character Observation of Bubble Rising in Vertical Gas-Liquid TwoPhase Flow
The study of bubble motion in water is a basic subject in gas-liquid two-phase flow research. A suit of visualized experimental device was designed and set up. Bubble rising in stagnant liquid in a vertical translucent rectangular tank was studied using the high-speed video system combined with digital image process methods. Several bubble parameters were calculated base on the processed images. Bubble track, bubble velocity curve and accelerating curve have been plotted at different working situation. The movement of bubble rising in water was observed. And the dynamics of bubble were summarized with experimental analyzing. Both gas orifice diameter and bubble detachment are mainly influencing factor for bubble size and bubble dynamics.
