Abstract

Gas-liquid flow can be separated by using a swirl separator. One of the interesting parts to be investigated in the swirl separator is the influence of the pickup tube diameter. Therefore, its influence on the gas-liquid flow behavior inside a vertical pipe equipped with a static swirl separator element is investigated in this study by using computational fluid dynamics (CFD). Euler-Euler approach simulating water as the continuous phase and air as the dispersed phase was selected in this study. The difference in the gas-liquid flow characteristics observed in the simulation using 4 mm, 6 mm and 8 mm diameter of the pickup tube is presented and discussed in this study.
