Abstract

This report reviews the authors' recent works on detailed numerical simula- tion of bubbly flows using the volume of fluid method, which is based on local instantaneous field equations and an interface tracking scheme. Shapes and rising velocities of single bubbles, Taylor bubbles and two bubbles in train in various stagnant liquids were calculated and compared with measured data. Bubbles in a shear field and a laminar flow were also simulated to examine whether we can obtain appropriate bubble distributions in a bubbly upflow. 1 Introduction Due to the existence of complex moving boundaries, most of the numerical simulations of gas-liquid two-phase flow have been bas
