Local-scale Multiphase Flow in GLAD (Gas Lift Advance Dissolution) System

Abstract

We have been developing GLAD (Gas Lift Advanced Dissolution) to sequestrate CO_2 at the deep ocean. Local-scale structure of a multiphase flow, such as interfacial motion of individual bubbles, fluid motion in the vicinity of then and their interaction, is strongly required to obtain the best condition for the operation of the system. At the present paper, we will discus surrounding fluid motion of a single bubble zigzag rising in a rest water column on the basis of experiments using LDA and PIV.
